Contractors provide service to customers with many different system applications in the field with an even wider variety of capacity requirements. Today, the number of refrigerants that a contractor might encounter is simply never ending! While not every system is fitted with a TEV, there are literally thousands of different TEV variations in the market place.
Can you imagine how hard-pressed wholesalers are to stock every version of a valve that might be needed for routine service? This is mind-boggling and needless to say, the contractor is even more unlikely to have the right valve on a service truck for that emergency service or repair job.
How does a contractor or wholesaler solve this problem?
Turn to Sporlan’s interchangeable cartridge style TEV product line, the type Q and BQ. Simply select the thermostatic element, the body and the right sized cartridge for the application and assemble the parts. They are even available with conventional (Q) and balanced port (BQ) construction. These easy to select and assemble valves mean you’re always carrying the right valve for the job.
Carry the Sporlan Q and BQ valve on your truck and stay on the job…not cruising around looking for parts! You save time and keep customers happy. It is simple. It is easy. It is economical. It just makes sense.
What are the advantages of the Q and BQ thermostatic expansion valves?
The mix-and-match components of the Q and BQ product line satisfy thousands of applications. With access to these components, you will be able to assemble valves that are just right for most refrigerated cases, coolers, or freezers and even air conditioning applications.
What is involved in the valve assembly?
It is really very easy. Select the correct thermostatic element, the right body assembly and finally pick the cartridge required to handle the system load and thread them all together. Sporlan has easy to follow graphical instructions and literature.
What is so special about the way the cartridge is installed in these valves?
The Q and the BQ valve cartridge is installed through the top of the valve body. This unique design means these valves can use ODF solder or SAE flare fittings. It also means the valve capacity can be changed with a replacement cartridge and the connections can be left undisturbed; simply isolate the valve from system pressure and have at it. No need to remove the Q or BQ valve from the system.
How do I make sure I have the right sized valve?
With 7 different cartridge sizes for the type Q valve and 5 different sized cartridges for the balanced port type BQ, including a bleed port option in 4 of the BQ cartridges, you have many options available to put the right valve together for the job.
What types of refrigerants are compatible with the Q and BQ valves?
The Q and BQ valves are compatible with the new refrigerants on the market, like R-448A and R-449A. They are also compatible with R-22 and the common replacements such as R-422D, R-407A, R-407C and R-407F. And the BQ with its balanced port construction is perfect for high-pressure refrigerants like R-410A.
The replaceable thermostatic element feature increases the flexibility of the Q and BQ thermostatic expansion valves. This allows the thermostatic elements to be replaced during system conversions to a new refrigerant, or for service, without replacing the valve or removing the valve from the system.
Why should I carry a Q and BQ TEV case?
Carrying a stocked Q or BQ TEV case helps prepare contractors and service technicians for most situations - eliminating costly trips back and forth to the wholesaler and special orders. The case can be customized with the components in the greatest demand. With just the components supplied in the Q or BQ case, you can configure valves to satisfy over 100 unique applications.

EMI shielding gaskets such as conductive elastomer gaskets come in many different materials and almost a limitless number of shapes and sizes.
They are most commonly made of a base material of silicone or fluorosilicone with added conductive fillers such as silver, silver-plated aluminum, nickel-plated graphite, and others. Conductive elastomers represent one of the most versatile products in the category of EMI shielding gaskets.
From a manufacturing perspective, there are two key processes used to create these gaskets: splicing and molding. Check out the detailed list below for information about choosing the process that makes the most sense for you.
Conductive elastomer gasket splicingConductive elastomer gaskets are often extruded in long strips, available in bulk or cut to specific lengths. To create custom sized O-rings, the extrusions are cut to the proper length and the ends are adhered (fused) together. Known as splicing, this process utilizes a proprietary adhesive to create an immensely strong bond.
Molding involves compressing uncured conductive elastomer material into a specially designed mold. The material takes the shape of the mold and retains this shape when cured.
Between molding and splicing, there is virtually an endless number of profiles and shapes that can be developed. For more information on choosing and designing an EMI shielding gasket, check out the Conductive Elastomer Handbook below.

Pressure Sensitive Adhesives and Elastomer EMI Gaskets: What You Need to Know
Securing leak-free connection of impulse lines to manifolds for applications that use differential pressure flowmeters is a subject that has taxed instrumentation engineers for more than a century. Back in 1910, when the very first orifice plate installations made an appearance, they involved 33 connections and 16 lengths of tubing! Thanks to the development of highly integrated manifolds, today’s installations often only require just two tube connections. However, ensuring the long-term integrity of these connections remains a contentious issue.
The first manifolds on the market used NPT taper threads for their tube connections. Despite being the bane of installers’ lives, this type of technology continues to enjoy widespread use today, with most manifold manufacturers still offering it as an option. But much better tube connector technologies are now available.
What’s wrong with taper threads?Unlike compression type tube fittings with one or more ferrules, taper thread fittings rely on the threads themselves to provide the seal. During make-up, progressively larger diameter threads on the fitting are compressed into progressively small diameter threads on the manifold, until eventually there is no clearance left between the crests and roots of the threads and they effectively form a metal-to-metal seal.
NPT taper thread fittings are popular because they are relatively inexpensive, but they also have distinct disadvantages. The fittings cannot easily be installed with a specific torque, which makes it all too easy to crack or distort the female part by applying too much torque, or to apply too little, resulting in potential leak paths due to incorrect thread cling. There is also always some thread clearance due to manufacturing tolerances, which means that if the fitting is not tightened to the point where thread deformation creates a metal-to-metal seal, there is a spiral leak path. Furthermore, the upper and lower machining limits of NPT taper threads mean that there might only be two turns of thread engagement in an assembled connection; the most reliable means of preventing this is to use, if possible, a matched pair of male and female parts produced by the same manufacturer.
Taper thread can suffer from limited thread engagement
Another major disadvantage of NPT fittings is that their radial orientation cannot easily be adjusted without compromising connection integrity.
Most installers of NPT fittings elect to use some form of thread sealant to help prevent leaks. This usually comprises a fluid carrier which transfers a filler compound into the threads and then cures. Unfortunately, not all sealants act as lubricants and they are also very easy to misapply. Too much sealant can cause system contamination, which can result in unseated valves or blocked lines, while too little can allow the threads to gall (cold weld) during installation, requiring replacement of the entire manifold and tubing system. A further problem is that the fitting cannot be adjusted once the sealant has cured.
A popular alternative approach is to use PTFE tape as a sealant. This additionally acts as a lubricant during assembly and facilitates tighter connection of taper thread fittings – although it can lead to over-torquing. Another issue with PTFE tape is that it has a tendency to shred and cause system contamination. For this reason, its use is often prohibited in sensitive instrumentation systems.
Parker now offers two manifold connection solutions – PTFree connect and inverted A-LOK – which completely eliminate the need for taper threads, PTFE tape and thread sealant.
PTFree connect™Our PTFree connect system provides a simple means of connecting impulse lines to manifolds without involving the use of taper threads, PTFE tape or thread sealant. Available as an option for every type of manifold valve block that Parker produces, PTFree connect offers different versions that accommodate metric tube sizes from 6 to 12 mm and imperial sizes from 1/4 to 1/2 inch.
Manifolds fitted with the PTFree connect system are exactly the same as their standard counterparts, except that their inlet/outlet and drain/test ports can be factory fitted with male adapters, supplied complete with a preassembled nut and ferrule(s). The (parallel) thread on the male adaptor is screwed into the manifold and uses the same type of stainless steel sealing washer as the valve heads, to provide a high-pressure leakproof and bubble-tight connection. The adaptor is securely locked by a cam or locking plate mechanism. We have used this connection principle well over a million times, so you can be confident that it’s a tried and trusted system.
Installation of PTFree connect manifolds is simple. A variety of connection bodies can be used – including straights, elbows and tees – and all angled components can be freely swivelled to facilitate secure positioning. And if anything does go wrong during installation, the sacrificial element is the male adapter – not the manifold – so the cost of remedial action is considerably less than with any other type of connection.
Inverted A-LOK fittingsMore recently, we developed inverted A-LOK fittings, designed specifically for connecting impulse lines directly to manifolds. Like our PTFree connect system, these also eliminate taper threads and the need for PTFE tape or thread sealant, but they do not involve the use of adapters – the tube is fitted directly to the manifold. Each of the two manifold ports forms the female half of a connector and is machined with a cone-shaped orifice and a standard parallel (non-tapered) thread. Each male part comprises a tube and an inverted nut, with threads on its outside surface, which drives two ferrules forward during assembly; the pressure seal is provided by the front ferrule – not the threads of the connector.
Inverted A-LOK fittings facilitate direct-to-manifold connections
A key advantage of our inverted A-LOK fittings is that the tube is not twisted during installation – all make and remake motion is transmitted axially to the tubing. Since there is no radial movement of the tubing, it is not stressed and its mechanical integrity is not compromised. These fittings are suitable for both thin wall and thick wall tubing, can be used with a wide variety of tubing materials and accommodate repeated disassembly and remake. However, they still require careful installation. If the internal cone becomes damaged, the manifold block will need to be replaced. And due to cross-hole drilling in the block, the technology is not available on all types of manifolds.

Have you had problems with your polyurethane seals degrading, especially when exposed to higher heat creating the need to replace your seals more often than you would like? As you probably know, seal replacement creates costly downtime that can be avoided if you have an appropriate seal for the job. Parker's Resilon® 4350 polyurethane is up for this task. Resilon 4350 is designed for sealing at higher temperatures up to 250°F continuous and can withstand short-term excursions of up to 300°F without leakage.
Resilon 4350 polyurethane was formulated to extend the high-temperature capability of Parker’s proprietary urethanes. Where current, more ordinary polyurethane seals have failed, Parker’s new Resilon 4350 has the highest temperature rating of any specialty polyurethane on the market. It was developed for applications where high temperatures or extended heat history cause failures with current polyurethane seal materials.
In a head-to-head comparison test at 250°F continuous, the Resilon 4350 material presented minimal leakage (< 5 grams) up to 250,000 cycles during a life test. This equates to a 33% longer lifespan compared to the standard 4300 material at this elevated temperature range (Figure 1).
Additional testing was completed showing the % seal force retention as the external temperature increased from about 160°F to 250°F. The three materials tested exhibited a linear relationship between the seal force retention and temperature. The Resilon 4350 had a 7-10% higher seal force retention beyond 4300 and the leading competitor of high-temperature polyurethane during this temperature range. The Resilon 4350 still exhibited a 20% seal force retention at 250°F (see Figure 2). Based on the results of this testing, this material is promoted as having a continuous operating temperature range of -65°F to 250°F.
Parker’s Resilon polyurethanes are provided in various profiles for use in a wide variety of applications. With the introduction of Resilon® 4350 the recommended operating temperature range for best performance can now be extended 20° to 25°F higher, giving design engineers the ability to push the envelope.

Thermal Capabilities & Polyurethane Seal Materials: What Do Temperature Ratings Mean?
In industrial manufacturing, the need for frequent, costly maintenance is often the stimulus that compels equipment operators to search for a better solution. Time is valuable, and hours spent on maintenance activities could be put towards other responsibilities.
This was the case when a cement company searched for a solution for the short life expectancy of the filters used in its Fuller pulse jet dust collector connected to and OSEPA high-efficiency separator.
The problem
The company was realizing a useful life of its process dust collection filters of only two years, due to a combination of issues: Velocity of the dust in their systems was rendering the membrane material on their filter bags useless. This was allowing for bleed through to the depth of the polyester filter bag, causing an increase of operating differential pressure to over 8 inches (203mm). The high operating differential pressure led to an increase in measured emissions from the system.
The original system was designed to handle an air flow of 61,000 cubic feet per minute. This called for 975 installed filters. Each filter was made of 16-ounce (500 grams) polyester PTFE laminated felt. The dimensions of each filter were 6.25 inches (158.75mm) by 144 inches (3,658 mm). This resulted in a total filtration area of 19,134 square feet (1,779 square meters.) The air to media ratio was 3.1:1.
The solution
The search ended when the company replaced the existing conventional bags and cages with Parker OSEPA BHA® PulsePleat® filter elements (PFE). PFEs offered the opportunity to increase total filtration area while reducing the physical space required. The same number of elements were installed but they were reduced in length from 144 inches to 57 inches. The spun-bound polyester media, set in a pleat, with molded urethane end-caps required no tube sheet or collector modifications. Due to the pleat design, the total filtration area was increased by 75 percent to 33,590 cubic feet. This reduced the air to media ratio to 1.8:1.
Results
After several months of operation, the cement company realized a number of savings and benefits, including:
By installing PFEs, the cement company avoided the high costs of modifying their existing equipment or adding a new dust collector. The company has realized full production capability with lower emissions, lower differential pressure, reduced energy costs and less compressed air consumption as well as longer filter life.

In an industrial manufacturing environment, t-slot framing is often used for workstations, machine guarding, enclosures, tables, carts and more. When you have your initial idea for building with t-slot framing, how do you convey the concept? Do you use a piece of paper, CAD or even the famous napkin to sketch out your thoughts?
Traditionally, and still today, the “napkin sketch” method is how most t-slot aluminum framing companies encourage the user to send in information. It is very effective and allows the customer to quickly convey their ideas.
Think it
You might notice a trend that takes the customer from the “paper napkin sketch” to the “electronic or digital napkin sketch.” With the increasing use of 3D CAD systems, customers can use electronic tools to create their designs. The user libraries can be downloaded from the web and all the parts and components become available for use in your CAD system. Some companies offer a plug-in to a specific 3D CAD system. This means that their software works with that specific 3D CAD system, which may or may not be the system that you’re using. Other companies offer a standalone tool that can export files into various 3D CAD formats.
Design it
Here are a few ways to access these tools
With so many projects and the time constraints that go along with them, it is important for users to work efficiently. Using an electronic tool to “sketch” your design will allow you to import that assembly into your current project. This is very valuable if it is part of a larger machine design. Also, being able to interact with a trusted partner to quickly receive a quote helps with the process of understanding project costs along the way.
Build it

Choosing Between Steel or Aluminum Structural Framing? Read this.
This blog post will describe current best practice or optimising the installation of a continuous position sensor (CPS) on to a pneumatic linear actuator.
For the purposes of the guidance, we’ll use the Parker P8S CPS (Continous Position Sensor) as a reference example. Despite being available in a range of configurations – including IO-Link or analog feedback signal, a choice of outputs and various measuring ranges – the installation procedure is common for all P8S types.
The P8S CPS is suitable for direct mounting to any T-slot cylinder. So, as a point of note, if another cylinder variant is used, such as a tie-rods or round body type, separate brackets will be required.
First of all, please appreciate that the CPS should be installed in line with the correct operating voltage. After all, there will clearly be differences between, say, an M8 analog connection versus an M12 IO-Link.
When ready to begin, move the position of the cylinder’s piston to the desired starting point – known as the zero point. Now you can insert the CPS into the cylinder’s slot or bracket, with the cable pointing back towards the zero point. To determine exactly where the CPS should be positioned, move the device until the yellow LED is illuminated. Then, slide the CPS away from the zero point until the LED turns off, and slide it back again to the position where it lights up once more. That’s your position for the CPS, so you can now secure it in place using the set screws.
Moving to configuration, this process can be performed using the teach button on the CPS. With the CPS correctly installed and the piston in the zero position, press and hold the teach button for two seconds. The LED should now blink and you can release it. The zero point has been stored in memory.
Next, set the piston position for the end point of the desired measurement range. Press the teach button once, and the measurement range has been stored. The analog signal or IO-Link process data is now configured to this range.
So far, so good. Now, move the piston from zero point to end point and check to ensure the LED remains lit throughout the travel. If you notice that the LED turns off at any point, simply repeat the configuration steps above.
To reset the measurement range to the maximum possible range, press and hold the teach button for five seconds. If you are deploying the IO-Link version of the Parker P8S, the measuring range can be configured using parameter commands, which also outline how the teach button can be locked out, for example. You can refer to the installation guides for more details on specific parameter commands.
All pretty straightforward - like anything it’s only easy if you know what you’re doing! Hopefully this short blog has proved useful in highlighting best practice when it comes to installing and configuring CPS sensors.

Products used in the rigorous oil and gas industry must be resilient and of high quality to properly support these complex operations. Hoses and connections need to be safe, versatile and efficient. Rubber hose has its limitations when used in harsh environments. One of the issues is inner tube blistering. The blisters are caused by fluid over time permeating into the rubber core tube. When the pressure is released quickly, the fluid tries to escape quickly and damages the rubber core tube causing blisters that in turn cause leak paths in the core tube.
Parker has developed a high pressure hose specifically for subsea applications. The core tube is made of nylon which is time and field proven to work in subsea applications, and it is chemically compatible with subsea control fluids.
The flexible alternative to 1-1/2” I.D.
The Polyflex 2340N-24 Hose is specifically designed for subsea applications in the oil and gas market. It is a flexible hose that meets API 17E and ABS requirements. The seamless, extruded Polyamide core tube has a wide range of media compatibility, making it suitable for blow out preventer (BOP) equipment and many other offshore drilling applications. 
The high tensile steel reinforcement provides a full 5000 psi working pressure at 4:1 design factor. These features, combined with the sea-water resistant polyurethane jacket, offer a hose solution that withstands the rigors of the oil and gas industry and exceeds industry standard requirements. It is also available in long, continuous lengths. This is important because it reduces connection points, which reduces leak points, reduces set up time and allows for smoother routing of the assembly. Fewer connection points mean better flow.
The 2340N hose serves multiple applications in the oil and gas industry, such as BOP stack, acidizing, well stimulation, cementing and land or subsea based hydraulic systems. For more detailed information please reference the product data sheet for 2340N-24 Polyflex High Pressure Hydraulic Hose for the oil and gas market.

A Deeper Look at Subsea Hydraulic Couplings
Large Capacity Piston Accumulators Help Subsea Engineers Meet Extreme Demands
Industrial settings with strenuous applications, such as thermal cycling and vibration, are recognised as some of the toughest environments for tube fittings. In all cases such applications demand highly precise, leak-free technology to ensure protection from vibration and thermal cycling. For example, in power generation, nuclear and chemical plants, worker and atmospheric safety is business-critical.
Engineers face numerous options when choosing tube fittings for instrumentation, process and control systems and equipment. In most cases, buyers need a solution that will minimise risk, prevent leakage and provide robust value for money.
In instrumentation installations such as impulse pipework, typically a three piece (single ferrule) or four piece (double ferrule) design is preferred. While both types of fittings have their own merits, the four piece fittings are slightly better known in the market. But in some cases, there are definite advantages for choosing a three piece, single ferrule design.
Benefits of single ferrule designsWith just three pieces required - a nut, body and single ferrule - this type of fitting is easy to install. The ferrule design also provides a strong anti-vibration hold on the tube.
Single ferrule fittings typically offer six core benefits:
1. Fewer leak paths
Many engineers constructing fluid or gas handling systems aim to eliminate potential leak paths. This approach also applies to the design of tube fittings.
With single ferrule fittings such as CPI™, only two potential leak paths need sealing. But double ferrule fittings have three or more paths to seal, depending on the fitting design and composition.
2. Sealing mechanism
With double ferrule designs, the front ferrule contacts the body seat over the entire surface. This causes the end load to be distributed over a wide area.
With Parker’s CPI™ design, there is less body seat contact; the end load is concentrated over a smaller area. Higher contact pressure enhances the ability of the single ferrule solution to seal low density gases, which means it can out-perform its double ferrule counterpart in some applications.
The CPI™ fitting also has the benefit of the one-piece ferrule, utilising Parker’s unique Suparcase™ system. This offers better corrosion resistance and is less likely to be damaged in service; but it’s not available on the front ferrule in twin ferrule tube fitting designs.
3. Dampening vibration
Tubing vibration can affect the ferrule seal. However, with single ferrule designs, a light compression grip at the rear of the ferrule isolates seal points from system vibration. This creates a cushioning effect, providing excellent vibration resistance – again, a potential advantage over double ferrule designs.
4. Better performance in temperature cycling
During temperature cycling, metals naturally expand and contract; this causes dimensional changes in fitting connections. With single ferrule fittings, the ferrule features a ‘spring loaded’ effect; this creates a constant tension between the fitting body and nut.
The spring action compensates for cycling changes. By storing excessive force in the bowing action of the ferrule, it maintains effective sealing points. There is no corresponding spring action with double ferrule designs.
5. Ease of installation
The CPI™ single ferrule tube fitting uses a Molybdenum Disulfide coated nut, which reduces the torque required to make up the assembly by as much as 40%. This coating also gives the added advantage of precise and consistent re-makes. As a result, the fitting can last longer in service - reducing potentially costly maintenance work.
6. Precision assembly
Both single and twin ferrule designs can potentially seal all leak paths, as long as they are assembled precisely. With double ferrule fittings, there’s scope for incorrect alignment, lining fittings up backwards, or leaving a ferrule out completely.
Ultimately, with fewer components, there is less that can go wrong; single ferrule solutions are quicker and easier to assemble, so the scope for error is reduced. With Parker’s CPI™, fittings are sold completely assembled and ready for immediate use.
Offering superior corrosion resistance, the CPI™ product series is manufactured to the highest quality standards and available in a range of sizes, materials and configurations. There is documented heat code traceability on stainless steel fittings for nuclear and other critical applications.

Mobile equipment manufacturers are always striving to get the most out of their machines without over burdening the system with costly and complex mechanics. Moreover, performance expectations are not only shaping machine needs, but also safety requirements. Consequently, this has driven many engineers to design closed loop systems featuring electronic sensors as feedback devices.
For example, manufacturers of lifting equipment such as truck mounted cranes, telehandlers and scissor are all striving to provide operators with safe work environments all the while maintaining the integrity of the lifting function during operation. The choices for detecting or measuring tilting/leveling conditions are vast. They range from purely mechanical devices: tilt gauges and bubble levels for simple visual indication to basic electronic sensors offering discrete tilt switch points. While these options are typically cost effective, they offer little to no feedback for safety or performance.
The Universal Tilt SensorDesign engineers increasingly relying on sophisticated sensor technology for fast accurate feedback and diagnostics during operation. Today’s systems require something more; electronic inclinometers that offer 
continuous monitoring of angular position in relation to a calibrated reference planes either horizontal or vertical. The latter can best be accomplished with Parker’s Universal Tilt Sensor (UTS).
The UTS, manufactured by Parker’s Electronic Controls Division, is a MEMS technology tilt sensor designed for configurability making. It is suitable for a broad range of mobile applications. The UTS communicates via SAE J1939 protocol providing fast and reliable angular information from either two or three axes. The patented 3-point setup and low-profile housing offer ease of installation, reduced build time and maximize install possibilities. Since some applications require a balance of speed and accuracy, the UTS also offers tunable filter settings to adjust the output response on command. Three factory variations are available by catalog today:
Most vehicles with lifting booms require the chassis platform to be level with the ground before the boom and load can be elevated above a certain point and/or rotated around its base axis. This helps ensure the safety of the operator and payload. A chassis mounted UTS can continuously monitor changes in inclination during the deployment of the stabilizing actuators (outriggers and jacks) to feed the control system real time information throughout the leveling process. This feedback can insure a uniform lift even on the most challenging terrain. While a system utilizing the UTS for auto level can be made simple as a one-touch function, it can also offer continuous monitoring of the chassis as different loads and mechanical movement adjust the center of mass of the platform. The continuous feed of information can provide real-time feedback on out-of-level conditions alerting the control system and operator of potentially danger inclination. Finally, the sensor provided an operator display a real-time visualize of tip and tilt for manual adjustments where needed.
In cases where the chassis has an over extended wheel base, i.e. ladder engine or multi-axle crane trucks, two UTS sensors could be used; one in the fore and one in the aft part of the chassis. By monitoring the pitch and roll condition of the chassis in two locations simultaneously, a machine can utilize the UTS output to prevent excessive twisting along its longitudinal axis of the platform frame thus preventing costly repairs to the machine.
This is just one of many ways the UTS can be used in a close loop system to achieve optimum performance and peak safety on mobile platforms. It has been built to operate in the most demanding marketplaces including agriculture, construction, material handling and more. Learn more about Parker sensors.

Stretch films are essential in the packaging industry as they provide a versatile and high-quality solution for packing products in a safe and economical way. Film is produced by a flat die extrusion process where AC motors and AC variable speed drives play a significant role in ensuring a high-quality output.
The process starts with the extruder that is essentially a pump that melts and transports fluids of high viscosity. The polymer enters into the extruder via a gravimetric feed, and through the combined actions of heat and mechanical stress, the material is melted, mixed and pushed through an extrusion head to give the desired shape. After exiting the extrusion head, the material enters a cooling unit, here water cooled ‘chill rolls’ reduce the temperature of the film before it is finally wound onto rolls.
ExtruderThe extruder consists of a hollow cylinder in which rotates a single or double screw driven by an electric motor; this is usually coupled to the plasticising screw by a gearbox. The motor provides the torque required and rotates at a speed necessary to obtain the expected melt flow rate. Any failure in the precise control of the screw speed can cause changes in film thickness in the machine direction.
For the past 20 years, AC motors have typically taken over from DC motors in the control of the extruder screw in cast film line applications. They have been able to deliver many advantages in terms of convenience, reliability, low maintenance and a reduction in the overall dimensions of the system solution. AC motors are controlled by AC variable speed drives that guarantee stable rotation - even at very low speeds (via a closed loop circuit through incremental encoders), provide short circuit protection (low or high voltage), and incorporate EMC filters to eliminate electrical noise and interference.
In recent years, along with AC motors and drives, torque motors have also been utilised in screw extrusion control. These offer a complete direct drive solution that does not require the assembly of different elements such as a gearbox, belts and pulleys. Torque motors guarantee uniformity in the motion, linearity and constancy in the extrusion of the plastic material.
Cooling sectionAs previously mentioned, when the material leaves the extrusion head, it is melted on chilling rolls that form the cooling section of the cast film production line. The cooling unit is comprised of a primary quenching roll, that cools the film on one side, and a secondary roll, that cools the film on the opposite side. It also includes a motorised roll positioning system for correct vertical and cross machine direction alignment of the rolls, and in many cases a vacuum box and/or air knife.
The rolls must be perfectly aligned with the web to guarantee uniform tension and to minimise thickness variations across the width of the film. In addition, the angular velocity of the rolls must be well controlled to prevent film thickness fluctuations in the machine direction.
Accumulator and winder section
Within the cooling and winding sections we find the accumulator, this is used to allow splicing of the web being fed from an empty winder to a full winder at zero speed without stopping the line.
At the end of the process, a further winder brings the extruder material onto rolls. The winding process has to preserve the film’s properties and dimensions when the rolls are unwound in other downstream processes.
There are several different types of winders, although the typical one used one in cast film applications is a ‘turret’ or ‘centre’ winder where the web tension decreases as the roll diameter increases.
All the movements performed in the cooling, accumulator and winder sections are driven by AC motors and drives that govern the web speed and the correct web tensioning.
AC Drives and Motors
AC Drives with high-end control are very important for guaranteeing high-quality film throughout the process. Easy-to-configure software for the closed loop control and optimum efficiency for many different types of material is a vital element of a cast film line system and process.
Parker's AC30 series with power ratings ranging from 0.75 to 450 kW coupled with the company’s Quicktool software with full IEC61131PLC functionality or Parker DSE Lite software, provides all the features needed to achieve optimum synchronisation between all line sections. It allows customers to create, parameterise and configure user-defined applications using dedicated function blocks such as the winder, PID and diameter calculator. The AC30 series also provides access to a large library of application macros and worked examples.
Connectivity via EtherCAT, Profinet, Ethernet IP and Modbus TCP IP through a dual Ethernet port enables communication between individual drives in a simple and flexible way and supports intelligent data analytics and connection to external servers. The line setpoint can be sent through a very fast channel supported by 1588 time synchronised peer-to-peer communication, and each part of the machine has its own regulation, either within the drives, or through communication protocol by the PLC.
An animation shows how high a performance drive solution supports the optimal control of a cast film line.

Check valves are unseen and undervalued. These valves are found in just about every mobile and industrial hydraulic system on the planet. Simply put, if there’s a pump, most likely you will find a check valve. Check valves keep the fluids flowing in the desired direction to prevent damaging flow or pressure in the reverse direction. They can also be used in applications to maintain a system pressure for optimum system readiness and performance. Surprisingly, for a valve that performs such a critical function, a check valve incorporates very few components - the body, poppet, spring and retainer.
Give this essential valve its due
Considering its wide use, engineers, maintenance technicians and even end users should have a basic understanding of the function that this essential component serves in their systems. More often, however, that’s not the case. Generally, misunderstood in their function and importance, when you mention check valves, the responses range from “they just don’t work” to “never use them.” As stated earlier, a check valve exists to keep fluid flowing forward while helping to prevent reverse flow of fluids within a system. That makes them important for many reasons.
Where and why to use a check valve
Like any product out there, quality makes the difference. When that product is a check valve, you want the best on the market. There’s just too much at stake to consider anything else. That’s where Parker comes in. Parker’s check valves are engineered to perform under the most demanding circumstances. Offered in many configurations, our in-line style check valves are available in a variety of sizes, pressure ratings, flow capacities and crack pressures to satisfy most hydraulic system applications.
• The DT Series check valves cover the widest variety of applications. These hard seat check valves are offered in sizes from ¼” to 1-1/2” with the added benefit and convenience of compact design. Select sizes are also available in 45°, 90° and tee shape fittings which can help optimize system design by reducing labor and leak points. If you are unsure where to start looking for check valves, the DT Series is a great first option.
• The CV Series check valves are another hard seat check valve option for your application. Built using a rugged modular design that results in less pressure drop for increased performance in critical applications.
• The CPIFF Series check valves are a soft seat check valve option for your application. Soft seats are often used in applications where zero backflow is allowed.
Many standard configurations are available for purchase on parker.com. In stock items can ship within two business days. Learn more about Parker's complete line of check valves. Contact Quick Coupling Division for custom configuration options.
One of the most important valves for any system
Finally, a check valve is a relatively inexpensive component that protects significantly more expensive system components. A company can save thousands of dollars by implementing check valves and protecting these vital components. With so much on the line, it only makes sense to choose a reliable and high-quality product that can deliver under the most extreme conditions. And that’s what you can expect from Parker.

Avoid the Most Common Workplace Hazards with a New Way to Change Oil
Technology advancements and new to world discoveries are constantly creating a new series of challenges for seal materials in the Oil and Gas industry. In today’s environments, seals are being pushed to perform in temperature, pressure and chemical extremes never before thought to be obtainable with rubber products. Application pressures exceeding 20,000 psi, service temperatures ranging from -40°F to upwards of 500°F and exposure to some of the most aggressive medias on the planet are placing immense amounts of stress on sealing elements. Parker’s FF400-80 compound has been formulated to provide a solution to all of these sealing challenges.
An Achilles heel of perfluoroelastomer (FFKM) compounds has long been lack of low-temperature flexibility and resilience. In a sealing application, the ability for a material to push back on the mating hardware is called resilience and is very important to prevent a leak. A method of measuring a rubber compound's low-temperature resilience is by performing a temperature of retraction test per ASTM D1329. See Parker’s O-Ring eHandbook for more information on low-temperature effects. Parker’s FF400 compound has a best in class TR-10 temperature of -23°F (-31°C). This property gives FF400 the low-temperature performance never seen before from an FFKM compound. The FF400 offers low temperature sealing capability approximately 45°F below a standard FFKM compound and has an overall recommended service temperature range of -40°F to 527°F. This low-temperature capability can be extremely valuable for surface equipment such as valves but can also give an advantage in high pressure applications where the glass transition temperature can shift causing a loss of resilience and flexibility.
FF400 also offers excellent resistance to Rapid Gas Decompression (RGD) damage. This compound has passed multiple industry standard RGD tests with perfect ratings of 0000 in multiple cross-sectional thicknesses. This characteristic is very important in applications such as compressors, valves, pumps, and various subsea equipment where a rapid reduction in gas pressures can cause significant damage to the seals. Having tested at multiple cross-sectional thicknesses, FF400 ensures that no matter the seal size the compound will resist damage caused by rapid gas decompression. It is very common for industry standard requirements such as NORSOK M-710, ISO23936-2, and TOTAL GS EP PVV 142 to be required by customers before a compound is considered for use in an application. Test reports and certifications can be supplied for FF400, as well as several other compounds, by Parker O-Ring and Engineered Seals Division’s Applications Engineering team.
Lastly, Parker’s FF400 compound provides an extremely broad compatibility spectrum for the harshest of oil and gas medias. Fluids such as crude oil, water, acids, aromatic hydrocarbons, bromides, brines, amines, and various gases are commonly seen in the oilfield and all can cause issues with rubber sealing compounds. However, one of the most common that is inquired about is compatibility with hydrogen sulfide (H2S) due to its toxicity, corrosive nature, and its presence of various concentrations in naturally occurring oil and natural gas reservoirs. Known also as Sour Gas, the higher the H2S concentration the sourer, more corrosive, and more aggressive the fluid stream becomes for sealing materials. Parker’s FF400 is a great option for these sour gas applications as it has the ability to resist chemical attack, and performs where H2S concentrations can be found at 20% and higher. All of these characteristics make the FF400 an optimal solution for use in compressors, pumps, valves, down hole tools, subsea chokes and other critical devices across the oil and gas industry.

One of the longest running Parker Motion and Control Laboratories (PMCL) is supported by the Mechanical Engineering Department at the University of Akron (UA). It was established more than 25 years ago in 1994 with hydraulic and pneumatic trainers. Since the dedication of the PMCL, Akron has experimented with several different Parker products such as our PID controllers (electronic modules). In later years, the university upgraded to more sophisticated controllers such as the PMC-100 controller followed by Compax3 controller for hydraulic motion control. Today, their emphasis in the lab is focused on the Parker Automation Controller (PAC) based flexible manufacturing cell control. PAC units provide a lot of flexibility in the lab in terms of availability of several programming languages, as well as their capabilities to handle vision based feedback for motion control. This transition was implemented due to the shift in evolving technology, which allows students to work on practical, real world experiments.
Each mechanical engineering student runs at least one motion and control experiment in the Parker lab. This experiment is part of the required course “Mechanical Engineering Laboratories.” In addition, other required courses such as “Senior Design,” “Control System Design” and “System Dynamics and Response” also make use of the lab. Each year approximately 200 graduating seniors run at least one motion and control experiment, which not only enhances their classroom learning but also exposes them to different Parker technologies.
Annual fluid power competition
The Parker Lab also serves as a design and manufacturing location for the NFPA Fluid Power Vehicle Challenge Competition. Student design teams participate in this competition every year since it began - almost 15 years ago. Students sign up for the required “Senior Design” course while they work on this project. When Parker originated this competition, we called it affectionately the “Parker Chainless Challenge.” Akron will attend this year’s challenge, let’s all wish them well!

Cleveland State University (CSU) and Parker recently announced a major investment in support of Say Yes to Education, a community-wide effort to make college attendance and graduation accessible to more local Cleveland public school students.
This year, Cleveland was designated as the fourth Say Yes to Education city, a national initiative that seeks to revitalize communities by helping to provide every public high school graduate access to college or other post-secondary scholarships, with local support of additional services to develop the gifts and talents of each individual.
This $5 million investment, part of an existing financial commitment from the Parker Hannifin Foundation, will establish the Parker Hannifin Learning Community at CSU, which will provide Cleveland Metropolitan School District (CMSD) students studying at CSU with two years of free on-campus housing. Providing on-campus housing will reduce a significant economic barrier many students face when pursuing a college degree and enhance student retention, which studies have shown greatly improves when students live on campus, particularly as freshmen and sophomores. The Parker Hannifin Learning Community will also offer a mentoring program to match students with faculty and peer mentors and directed career preparation activities such as job analysis support, internships, co-ops, and hands-on research projects.
The investment was announced at an event at CSU on March 6, 2019, which was attended by key leaders from Parker, CSU, CMSD and Say Yes, as well as students and members of the local media. It is aligned with a broader community effort to support the Say Yes to Education initiative, for which local businesses and community organizations have already raised more than $80 million.
“Parker is proud to support Cleveland State University and Say Yes to Education by strategically investing an existing commitment that will have a great impact on the future success of Cleveland public school students. This initiative further strengthens our long-standing relationship with Cleveland State University and is aligned with our broader commitment to help improve education.”
Tom Williams, Chairman and Chief Executive Officer, Parker Hannifin
The gift from Parker is a component of a broader commitment to CSU, which has funded the construction of the Parker Hannifin Administrative Center and Parker Hannifin Hall on campus, as well as the creation of the Parker Hannifin Scholars Program to provide academic scholarships to students.

A refrigerant distributor is a device connected to the outlet of an expansion valve when paired with a multi-circuit evaporator. The outlet of the distributor is machined to accept tubing which connects the distributor to each evaporator coil circuit.
A portion of the liquid refrigerant passing through the expansion valve normally flashes, resulting in two-phase (liquid and vapor) flow at the valve outlet. This mixture is predominately liquid by weight, but the vapor occupies most of the volume. An additional problem arises due to the fact that liquid and vapor move at different velocities. This is sometimes referred to as slip, since gravity has a greater influence on the liquid portion of the flow than the vapor portion.
If a simple header is used instead of a refrigerant distributor, circuits will not receive equal amounts of refrigerant. This is because there is a natural tendency for the liquid and vapor to separate, resulting in unequal amounts of liquid being fed to the various circuits. Gravity will pull the liquid to the lower circuits, and vapor will go to the upper circuits. This will lead to hunting from the expansion valve and possibly cause flood-back issues.
To achieve proper distribution, the liquid portion of the two-phase flow must be divided equally to each evaporator coil circuit. Two-phase refrigerant flow leaving the expansion valve enters the distributor nozzle. The nozzle increases the velocity of the two-phase flow, mixing its liquid and vapor components. Furthermore, the nozzle is positioned such that flow is focused onto the dispersion cone, equally dividing the mixture into passageways spaced evenly around the cone. The refrigerant is then transferred to each evaporator circuit through the distributor tubes.
To ensure equal refrigerant flow, it is important to size the distributor nozzle and tubes to match the system capacity as closely as possible. By doing this, the proper pressure drops and velocities are created to completely mix the liquid and vapor.
In addition to feeding equal amounts of liquid and vapor into each circuit to utilize the full capacity of the evaporator, each circuit must be equally loaded. Figure A is a schematic illustration of typical temperature conditions in the evaporator when both equal distribution and equal loading occur.
Figure B illustrates the same evaporator but with the air flow (and thus the load) less over circuit #3. The load imbalance will be indicated by low superheat at the outlet of circuit #3, and high super-heat at the outlet of circuits #1 and #2. Other symptoms are lower than normal suction pressure, reduced evaporator capacity and expansion valve hunting with possible flood-back.
Optimum distributor performance is obtained when the distributor is mounted directly to the expansion valve outlet. If the distributor cannot be mounted directly to the valve outlet, it can be connected by a piece of straight tubing. The tubing should not exceed two feet, and it should be sized to maintain high refrigerant velocities. Elbows located between the expansion valve and distributor hinder proper distribution, and are not recommended. The expansion valve should be tied to a single distributor. Multiple distributors on a single expansion valve results in poor refrigerant distribution in the evaporator coil.
A distributor can be mounted in any position. If the system operates over widely varying conditions, best performance is usually obtained when the distributor feeds vertically upward or downward, see Figure C. For applications where the distributor is not mounted directly to the expansion valve, the vertical feed arrangement is recommended.
When planning a system refrigerant conversion, it is critical to consider nozzle and tube sizing due to differing net refrigerating effects of refrigerants. For complete sizing and application information refer to Parker Sporlan Bulletin 20-10.

For more than 100 years, the car has simply been used as a device for transporting a driver and passengers from point A to point B at speed with minimum effort.
With the introduction of Advanced Driver Assistance Systems (ADAS) and other semi-autonomous driving technologies, a different concept of the vehicle is emerging. In the future, the car will be a media playback center, telephone, office and extension of the home’s living room which also happens to be able to convey passengers from A to B.
This is having a profound effect on the characteristics and on the sheer number of electronics systems in new vehicles and this in turn will dramatically extend the demands on the EMI shielding devices used to attenuate the radiated emissions that could affect circuits in the car. EMI shielding materials will need to perform over a wide range of frequencies, in more applications as electronic systems take over more and more aspects of the car’s driving operations, while adding as little as possible to the weight of the vehicle.
The time for OEMs to consider the options for achieving EMC in new car designs is at the start of a new design project, before the electrical and mechanical features of the vehicle’s systems have been decided. This gives design engineers the opportunity to bring considerations of EMI and shielding devices into the design process and enable optimization of the size, cost and performance of EMI shielding in the final system.
Top challenges of next generation 5G networksThe first challenge for automotive design engineers is the range of frequencies that need to be attenuated will be far greater in new cars than it was in the past. Until recently, the main frequencies of interest were the AM and FM bands used by radio and frequencies below 3GHz used by Bluetooth radio and mobile phone networks.
With the future introduction of 5G mobile phone network coverage, frequency coverage of EMI shielding materials will need to be extended. A higher frequency range is not the only issue. Cars are also going to support a much greater number of wireless communications systems within the vehicle.
The second challenge is that the effectiveness of EMI shielding is likely to be more tightly specified in the future as automotive manufacturers move towards a strict view of the functional safety of the electronics systems in cars, codified in the ISO 26262 functional safety standard.
So, what does this mean for the specification of EMI shielding materials?
Parker Chomerics maintains an intensive research and development program aimed at producing new filler materials for electrically conductive elastomer products. An important goal for this research program is to produce EMI gaskets that can cover the broader frequency range of interest in autonomous vehicles, while maintaining the desirable mechanical characteristics. Parker Chomerics CHO-SEAL conductive elastomers are widely used in automotive systems and offer useful properties, including resistance to high temperatures and contaminants, and the ability to provide environmental sealing to protect circuits from the ingress of liquids.
These elastomer gaskets resist compression set, accommodate low closure force, and help control air flow. They are available in standard sheet form, extruded or custom shapes.
In addition, Parker Chomerics CHOFORM Form-In-Place automated EMI gasket material can be dispensed directly onto castings, machined metal and conductive plastic and is widely used in tightly packed electronic housings. This advanced technology allows dispensing of precise positioned gaskets in very small cross sections and can free up valuable packing space of up to 60%. CHOFORM offers excellent shielding effectiveness which exceeds 100dB between 200 MHz and 12GHz.
New opportunities for weight savingThe development of autonomous and semi-autonomous vehicles is leading to a huge increase in the number of electronics modules per vehicle. This increases the scope for car makers to reduce weight by replacing conventional metal housings with lighter conductive plastic housings. While the weight saving on each module might appear small, when multiplied across the 100 or more electronics modules, the total weight saving becomes invaluable.
Parker Chomerics PREMIER™ PBT-225 is a single-pellet conductive plastic for use in automotive housings. PREMIER PBT-225 offers excellent resistance to hydrolysis when exposed to extreme temperatures and provides for easy processing and uniform filler dispersion. As a result, EMI housings made from PBT-225 offer tightly controlled electrical and mechanical performance throughout complex geometries. A weight saving of 30% is also possible when replacing an equivalent metal or aluminium housing with PBT-225.
By collaborating early in development projects with Parker Chomerics, automotive system designers can ensure that their electronic and mechanical design is optimized for shielding purposes.
