Quick connections for high-pressure, hydraulic applications have evolved immensely over time to satisfy new processes and operational needs. As industries advance their capabilities, the demand grows for coupler capabilities. Today, couplers must ensure fluid handling applications meet both safety and regulatory standards while simultaneously provide optimized containment of a wide range of fluids that can have different operational conditions.
Operators have continually depended on reliable connections for a “non-spill” experience under the most extreme conditions, such as temperature or high pressure. Manufacturers saw this as an opportunity to introduce new and enhanced couplers to the market.
Flush face valving delivers near-zero spillageCouplings, specifically non-spill, are engineered to combat hydraulic leaks and spills with a unified design incorporating sophisticated components. For reference, the term “non-spill” regarding a coupling means a specific type of connector can reduce fluid spillage to near zero whenever a coupling is connected and disconnected. Designed initially as heavy-duty metal couplings for high-pressure, industrial applications, non-spill couplings have evolved into a variety of materials to complement a wide range of applications requiring minimal spillage and air inclusion.
The flush face design became a significant advancement in quick coupling architecture. A “no-drip” valve means no more than a coating of liquid will appear on the valves’ surface, establishing repeated dripless connections and disconnections for a cleaner, safer work environment. Also, inclusion, which represents the air put into the fluid system during each connection, is drastically reduced through a flush face valve. The benefits of near-zero spillage and air inclusion have become critical in many applications, from heavy-duty construction equipment to hydraulic hand tools and general industrial machinery.
Parker’s non-spill quick couplingsParker is the global leader in quick couplings, delivering a spill-free and lasting performance, with a wide range of non-spill coupling solutions to fit versatile fluid applications. The FEM Series, FET Series and 59 Series all provide minimal fluid loss and air inclusion, as well as chemical compatibility when necessary.
FEM seriesThis non-spill quick coupling satisfies the design and performance requirements set forth by the ISO 16028 International Standards for quick coupling interchangeability. Featuring a push-to-connect design, FEM Series delivers an extra level of security for simple connections without causing any joining, crimping or soldering materials, eliminating spillage and air inclusion during connecting and disconnecting.
In addition, Parker provides an optional FEC male nipple, which allows connect-under-pressure capabilities with the FEM female coupler. This option is designed for applications where residual pressure makes connection difficult.
FET seriesThe FET Series non-spill quick coupling, engineered for reliable performance with equipment experiencing powerful impulses, accommodates the most demanding hydraulic applications. Parker’s FET Series couplings connect under pressure at 6,000 psi and disconnect up to 2,500 psi in environments that desire the security of a threaded connection under residual pressure. These couplers are built to operate under high-impulse mobile circuits, including excavators, and oil and gas equipment, such as umbilical lines and mobile drill rigs. Constructed of high-grade materials and a stainless steel valve, the FET Series features a robust Brinell resistant design and plating for extended durability and corrosion resistance.
59 seriesIdeal for use in high impulse applications with multiple high-pressure hydraulic lines, the 59 Series ensures consistent connections and disconnections under residual pressure. A powerful ACME thread utilizes a double start feature and allows a full connection to be completed in 2 – ½ turns, saving time and eliminating frustration. Its size and shape of the heavy-duty ACME thread make the coupling resistant to damage, easier to clean and ready for operational use.
An internal bearing between the collar and body eases resistance and minimizes the challenge of handling pressurized lines. In addition, the coupler and nipple have non-spill stainless steel valves and can be connected under pressure up to 5,000 psi and disconnected under a pressure of 2,500 psi.

How to Choose the Right Quick Coupling
Three Key Benefits of Using Non-Spill Quick Couplings
Screw-to-Connect Couplings Make Hard Work Easier
Since the advent of the semi-automatic water conditioning control valve followed by the automatic control valve, a common weakness has been the brine tubing connections between the brine valve and the brine tank. This circuit functions in two ways and is exposed to both a vacuum during the brine draw cycle and water pressure during a refill. A loose-fitting at either of these locations would cause loss of vacuum and/or a water leak, neither of which is acceptable and the result is often an unscheduled service call.
Results of poor connections during brine draw
Brine is drawn from the brine tank when the control valve cycles to provide motive flow and pressure to the injector assembly (venturi) in the control valve while simultaneously opening the drain line to allow displacement of the accumulated hardness and metals from the resin bed during the service run. An injector consists of a nozzle and throat. The injector is selected based on the size of the media tank square foot (ft2) surface area. A venturi combines a narrow tube called a nozzle that restricts the flow of water which increases the velocity and decreases the pressure of the water passing through it, creating a partial vacuum immediately after leaving the nozzle. As water passes through the injector nozzle, the high velocity creates a vacuum which draws the brine from the brine tank, mixing with the water as it enters the throat. The brine is mixed with the water to dilute the brine from 100% concentrated brine to a 30% concentration. This diluted brine is introduced into the resin bed where it releases the calcium and magnesium from the resin and flushes it to drain. Maintaining the proper mixture is very important to ensure optimal regeneration. If the brine draw is weak due to poor vacuum, the brine is diluted below 30% and the result is a partial regeneration and potential salty water to service after the regeneration cycle is complete. Further evidence of poor connections includes overflowing brine tank, where a complete loss of vacuum won’t permit brine draw. However, the brine refill cycle will add additional water to the brine tank which could result in an overflow condition. Different manufacturers offered what they thought was the best connector based on what was available at the time. Let’s look at some of the options that were available.
The different types of brine tube connections
Brass compression
Brass compression-style fittings were the most common and have been used for decades. In the early days, some valve manufacturers molded the 3/8” compression connection directly into the brass valve body produced at the foundry. The nuts, sleeves and tube supports were shipped with the valve to the assembler or were included with fully assembled softener/brine tank or cabinet style softeners. The brass compression-style connections are trusted for their dependable performance in virtually all conditions where temperatures range between 350 – 1200 F for domestic tap water applications. They also work very well for hot water softener applications where water temperatures can reach 1800 F. Attention to proper assembly is important because of the use of soft polyethylene or polypropylene tubing. Tube support is required to prevent distortion of the plastic tubing which guarantees effective gripping and a robust seal.
The connection is made by sliding the nut and sleeve onto the tubing, inserting the tube support into the plastic tube, inserting the tubing into the fitting until it’s bottomed on the seat, then tightening the nut until finger tight. The nut is then wrench-tightened with a specific number of wrench turns dictated by the specific fitting type and the size of the tubing. Based on their highly specific assembly instructions and the multiple components involved, brass compression-style fittings not only take time to assemble – around 40 seconds per connection – are labor-intensive - but also run the risk of being assembled incorrectly. For this reason, assemblers require some level of expertise when using this fitting type.
While brass compression fittings are viewed as highly dependable joint connections, with sealing performance that is second to none, higher labor costs are forcing manufacturers and assemblers to look for more cost-effective and less labor-intensive connection options.
Thermoplastic compression fittings
Plastic compression fittings have been used for over 40 years and vary in style and material composition. As with the brass compression-style fittings, tube support must be used with soft tubing. Plastic compression fittings are corrosion resistant and simple to install. The advantage is that there is no need to disassemble the fitting because all that is required is to cut the tubing square, insert tube support, insert into the fitting and hand tighten the ferrule nut to seal the connection. There is however a distinct disadvantage with these plastic fittings. They are prone to becoming loose with ambient temperature changes that coincide with seasonal weather patterns. Historically, it is necessary to retighten these plastic fittings to prevent the vacuum and water leaks previously mentioned.
Plastic Hose Barb Fittings
Plastic hose barb fittings are corrosion resistant and are not generally used for the brine valve connections. Typically, vinyl or polyurethane tubing or rubber hose is used with a hose clamp to ensure maximum grip and sealing power. Because vinyl or polyurethane or rubber hose is soft, it is subject to collapse during the vacuum phase of the brine draw cycle. Polyethylene tubing is not recommended because it will crack and leak.
Push-to-Connect Fittings
Push-to-Connect (PTC) plastic fittings for water service have been available since the mid-1980s. There are many companies that offer competitive products. Many of those products require a locking clip where a vacuum service is required to prevent the collet from retracting which allows the entrance of air. To combat this problem, some competitive products use a double “O”- Ring seal to solve vacuum-loss. The double “O”- Ring makes it harder to insert the tubing and unless full insertion depth is achieved by engaging both “O”- Rings, connection failure may result. Additionally, debris entrapment between the “O” – Rings may promote bacterial growth in the fluid stream. The problem of collet retraction may persist during vacuum service and therefore, a clocking clip may be required to prevent seal loss during vacuum.
An innovative alternative
Parker LIQUIfit fittings and one-piece cartridges feature a D-Seal that maintains a bubble-tight seal around the tubing to prevent liquid by-pass. The stainless-steel grab ring is fixed to the cartridge body which prevents the tubing from “pumping” or retracting during vacuum up to 28 inches of mercury (Hg) at room temperature without the need of a retaining clip.
The compact cartridge design allows machining or molding of a cavity for the cartridge which enables automation of manufacturing processes, reduces the labor cost of assembly, reduces leak paths, and gives your product or equipment a new, clean profile. By eliminating the need for threaded connections, tube connections are made quick and easy without the need or use of tools.
With Parker LIQUIfit, gone are virtually all labor costs associated with compression-style fittings and assembly time can be reduced by as much as 90%. Seasonal retightening of the plastic compression nuts due to temperature variations is no longer a concern. Hose clamps are no longer needed when using polyethylene tubing, and locking clips aren’t necessary to prevent retracting collets. LIQUIfit fittings and one-piece cartridges solve the challenges associated with other styles of brine tube connections and improve the integrity and reliability of your component, product, or system.

Vibrations might be inherent for industrial machinery, but in an automotive production plant, this could mean faulty products coming down the assembly line, leading to costly rework translating into downtime and delays in delivery. Whether you’re an automotive OEM or a Tier 1/Tier 2 Supplier, machine health is a huge deal.
Imagine the advantage of discovering a deteriorating process quality before real problems occur. Maintenance engineers, whose essential job is to prevent any disruption in the manufacturing process, could better plan the replacement timeline and make the necessary workarounds until new equipment is installed.
The Parker solution
To stay ahead of machine vibration and other issues, automotive factory engineers have turned to an early-warning system developed by Parker: SensoNODE™ Gold Sensors and Voice of the Machine™ software. This uninterrupted, real-time condition monitoring technology can be implemented throughout automotive production facilities to automate measurement taking and alert of trending situations. An additional advantage is the elimination of the tedious manual review of each device, freeing up the engineering team to attend to other tasks.
Parker’s robust automotive production machine monitoring system provides data that extends well beyond vibration. SensoNODE Gold Sensors monitor and transmit pressure changes, temperature, humidity, flow, current, displacement and analog signals—all to any internet-connected device via the cloud or localized edge applications. This Internet of Things (IoT) enabled solution allows plant managers to easily monitor process parameters that reveal changes in machine health as they develop, giving them the time and information needed to prevent failures.
Parker’s Voice of the Machine condition monitoring software provides machine alerts, status, and analytics in real-time on your desktop. The software can publish data to the cloud or most edge devices. The interface is simple to connect to the sensors, and measurements are displayed in a highly readable style. Users can customize dashboards and alarms. In only one click, data is sent via a .csv file to be shared from the cloud or via FTP on the edge.
Multi-department automotive plant monitoring
Pressure, level, temperature and other condition monitoring sensors can (and should) be implemented throughout automotive production facilities to automate measurement taking. They do so safely as well as providing early warnings of deteriorating process quality. Wherever a vital production process is taking place, SensoNODE Gold Sensors can ensure machines are operating at an optimum level.

Vibration in production assets such as robots is usually the result of worn gears or loose joints. A little lubrication or a mechanical tweak here and there can be a temporary fix, but they only delay the inevitable—a complete replacement of the affected machinery. Regular inspection of these huge machines requires a labor-intensive, time-consuming process to discover and address any issues before they become a real threat to production.
Recently, one manufacturer of trucks and SUVs that relies on robotics throughout the plant, looked to eliminate the inefficiencies related to the manual inspection. They called on Parker for a solution.
SensoNODE Vibration Sensors were placed on the joints of both new and older robots, recording vibration signatures in real-time. Measurements were compared on good and bad robots, establishing a threshold of when to service or replace a robot. Employing the Voice of the Machine software provided technicians with alerts of when thresholds were exceeded.
SensoNODE Sensors and Voice of the Machine Software provide this manufacturer with the ability to monitor asset conditions and view real-time data to diagnose issues before spiraling into a production catastrophe.
This is just one of many successful automotive industry installations Parker has performed. Maybe it’s time for your plant to get on board with this innovative technology.

Cloud-based Solutions for Monitoring Machine Performance
Highly sensitive instruments and equipment used in analytical chemistry and medical device applications require extreme capabilities. To provide unique differentiation of their products and meet their customers' challenging requirements, original equipment manufacturers (OEMs) rely on versatile state-of-the-art components.
One such component, the solenoid valve, provides precision control in gas and liquid handling applications. As market demand continues to push for increasing capabilities of these instruments, OEMs encounter the need for fluidic components that also push performance boundaries, such as lower leak rates, higher temperatures, and higher pressures.
This blog presents examples of how a high performance solenoid valve serves as a solution to challenging engineering requirements in critical applications such as gas chromatography and mass spectrometry (GC/MS), laser therapy and home hemodialysis.
Gas chromatography and mass spectrometry
Gas chromatography utilizes two physical properties of gases to separate and detect gas concentrations. The first of which is the boiling point. A small sample, often less than 1ml of liquid in size is prepared in a known solvent. The mixture is then presented against the near-vacuum of the flowing column causing the mixture to boil and enter the column (a long tube) in a predictable manner based on the pressure and temperature of the sample. The second property is the compound's mobility within the carrier gas of the flowing column. Compounds with a greater affinity for the carrier gas will reach the other side of the column quicker. At this point, in the case of a regular GC, the compound would reach a detector, be observed and measured. In the case of a GC/MS, the output of the GC is connected to an ionizing chamber of a mass spectrometer.
Mass spectrometry is again based on two physical properties of a compound, in this case, the molecular weight and the charge generated during ionization of the molecules in the compound based on the chosen ionization method. A mass spectrometer uses an electric field to generate or influence the flight of these ionized molecules. Since all molecules are influenced based on the charge that they have, the heavier molecules are affected less by being slower. These molecules are then detected usually by their charge at the end of their flight based on the time it took for them to fly that distance. Thus, this method is called the time of flight or TOF.
Since the basis for mass spectrometry requires the isolation of the molecular weight as a property, it is important that there be no resistive fluid within the chamber. A mass spectrometer must operate in a vacuum; different types of these systems require more severe types of vacuum. A solenoid valve with a very low leak rate, such as Parker's Series 9 Miniature Calibrant Gas Valve may be used to backfill the chamber with inert gas, such as nitrogen, during downtime or maintenance. This is especially important in a time of flight or cryogenic mass spectrometry where vacuums of 1 x 10-8 to 1 x 10-10 torr can be observed. This greatly reduces the pump downtime of a given system so long as nitrogen saturation is maintained between sessions since less vacuum boilable compounds can contaminate the system. A normally open configuration is also used as a safety mechanism in the event of a power failure.
Laser therapy coolant control
Laser therapy is used to treat everything from cancer to tattoo removal to reducing age-related skin damage. Lasers are used in one of three ways on the human body. They can stimulate repair and growth of human tissue in the case of anti-aging treatments, to focus on specific compounds in the cases of tattoo or hair removal, or for laser ablation therapy in the cases of cancer treatment and removal.
Laser treatment can be uncomfortable or painful, especially where laser ablation is required. That is why some companies have chosen to add the dispensing of refrigerants at the site of treatment as the laser fires. Refrigerants are expensive, have the potential to damage the atmosphere. Consequently, it is important to dispense the correct amount of coolant gas to the site. It is very important as well that no additional refrigerant escapes when the system is not in use. As many refrigerants degrade, small concentrations of corrosive gases begin to appear, posing a shortened lifetime to many materials. Because of its compact size, low weight and extremely low leak rates, the Series 9 valve is ideal in this application to precisely deliver the coolant when the device is in use. The valve can be built directly into the hand-held wand delivering the laser treatment so that the valve is right at the point of dispense and ensures that none of the coolant leaks, whether the unit is in use or not. This reduces the cost to the laser therapy operator and ensures that the patient and environment are minimally impacted using the coolant.
Home hemodialysis
With home hemodialysis, patients can be treated daily in their homes using much simpler, less costly equipment. The result is less patient discomfort and disruption of life. Technical challenges to this method of care are the ability to generate dialysate and dialyze at home. Originally, generating dialysate at home was done in small batches ranging from 5-20 liters. Advanced filtration was used to make sterile de-ionized water, which was then mixed with pre-measured concentrate, and shipped. Since the concentrate involved mixing, then testing, setup time was required prior to treatment
In the last 10 years, a new technology for on-demand dialysate has been introduced where the solution is generated using similar filtration technology and small amounts of the required chemicals are added as the mixture is tested, used and disposed of. The addition of these chemicals to the mixture must be in precise amounts — requiring fast response times and low internal leak. The need for sterility demands stringent external leak, and the corrosive nature of both dialysate and the sterilizing chemicals used to clean the devices after treatment requires corrosion-resistant hardware. The Series 9 is made of 316 stainless steel and has FKM seals to insure corrosive resistance to cleaning chemicals.
Conclusion
The Series 9 valve is a truly versatile product that has been proven to solve extreme engineering design challenges in some of the most innovative analytical and medical devices. Its low leak rate is rivaled by few other products on the market and its unique construction using non-corroding passivated 316 stainless steel and FKM seals render it a great match for aggressive chemicals.
The Series 9 valve can also be offered with analytically clean service or as part of an integrated sub-assembly module. Our expert team of engineers are available for further consultation regarding any required customizations.
Solenoid valves can be designed with a specific application in mind and over time become applicable to other applications due to its high quality and durability. In the Series 9 case, the valve was constructed with extremely low leak rates, high repeatability, non-corroding materials, high pressure and temperature, versatile fittings, orifices seals and voltages. In addition, the valve has the option to be built in a subassembly subsystem and analytically cleaned. All this is packed into a miniature lightweight design. The Series 9 valve is truly an amazing design that will continue to be used in different applications due to its remarkable versatility.

Any business relying on a fleet of vehicles to operate understands that fleet-related costs are one of the most substantial expenses it will incur. Most often, controlling these expenses is the job of the company's fleet manager. The fleet manager's job description is most frequently quite lengthy, but ultimately it all comes down to improving efficiency, reducing costs, and providing compliance with government regulations. The responsibility of keeping vehicles on the road and generating revenue rests squarely on this individual's shoulders.
By now, companies have reviewed the numbers from 2019. One line item highly scrutinized by management was more than likely 'Maintenance Costs.' Whether the bottom line is red or black, companies want to cut the costs of keeping vehicles on the road. Streamlining regularly scheduled maintenance is the most obvious place to make that happen.
What's a fleet manager to do?The responsibility for cutting costs in the maintenance department falls squarely on the shoulders of commercial fleet managers. So, where to begin? The labor-intensive oil change is an excellent place to start.
The frequency of oil changes is dependent on how a fleet operates. Typically, the low-end for oil changes are somewhere between 13,000-16,000 miles for heavy-duty vehicles and 3,000-5,000 miles for light-duty vehicles. It doesn't take long for most fleet equipment to rack up that amount of mileage, so scheduled oil changes are a significant part of a service department's routine.
In the past, maintenance technicians would spend hours removing plugs and draining oil into a container, then unscrewing the used filters--all while trying not to cause a spill that would have the EPA knocking on the door. Finally, out came a funnel, and fresh oil added to the engine. Fortunately for fleet managers and their technicians, new technology has made oil changes faster, safer, and cleaner.
Enter the Parker QuickFit™ Oil Change System
The QuickFit Oil Change System from Parker is a self-enclosed, single-point connection that allows oil to extract directly from the vehicle to the final waste containment. By employing the same connection point for extraction and oil refill, the oil change process is controlled and simplified, as well as eliminating any risk of safety hazards or spills.
When used appropriately, the QuickFit System greatly reduces oil spills, and because the system creates less consumable waste, it promotes environmental sustainability. The safety factor is significantly improved as well because less spillage means workers won't be slipping and falling.
In a recent article published on VehicleServicePros.com, Matthew Walley, product sales manager for Parker, advises that even with a closed-loop system, technicians need to be aware of all parts of the system. For example, making sure the hose on the other end of the fluid being evacuated is securely positioned in the final waste drum to prevent any spilling. Walley also mentions devices or features that can be included on fluid exchange equipment, such as non-spill valves, which can help prevent spills during the disconnect.
Time and safety—the big advantages
What are the advantages of the QuickFit System? First and foremost—TIME! Most oil change times are reduced by approximately 50 percent with Parker's innovative system. This time savings is due to its ergonomic design, which provides easier access within engine compartments.
Here are some staggering statistics: In the United States, data shows that a workplace injury occurs every seven seconds, and about 65 percent of all workdays or 95 million workdays are lost due to slips, trips, and falls. That's reason enough for worker safety always being on the mind of the fleet manager. Injuries mean downtime, and downtime equates to a loss of productivity and, ultimately, revenue. Employing the QuickFit Oil Change System improves safety conditions by eliminating spills and leaks, and that translates into fewer injuries to the maintenance team.
Moreover, with fewer connection points, the chance of an operator suffering a burn is lessened, as is exposure to fluids. The bottom line is the QuickFit System keeps workers safer, cleaner, and more productive.
A big win for the environment
In the United States alone, 61 percent of used oil is disposed of improperly. Since QuickFit eliminates all consumable waste, it's not just a big win for the fleet manager and the company. The environment, too, comes out ahead; the system makes it much easier for the maintenance department to adhere to strict regulations covering the disposal of used oil.
You'll never change oil the same again
So, as a fleet manager, is the QuickFit Oil Change System the right choice for your shop? The numbers speak for themselves:
Parker's QuickFit Oil Change System revolutionizes the process with a faster, cleaner and safer way to change engine oil. In three easy steps, technicians can purge, extract, and refill a vehicle's system with new oil without ever spilling a drop. This revolutionary process means money saved, and that’s a good thing for fleet managers when the year-end 2020 budget review takes place.

New Miniature Proportional Valve for Next Generation Ventilators
The Importance of Reliability in Diaphragm Pumps
New Product Technology Introduced in Point-of-Care Testing Instrumentation
Push to connect fittings have grown in popularity due to their ability to efficiently couple fittings to thermoplastic tubing while maintaining performance. Invented in 1969, push-to-connect fittings were first used for industrial pneumatic applications, typically at the point-of-use.
In 1997, that technology was applied to compressed air aluminum piping, creating the Transair® product line. The connection technology of Transair changes as the diameter size increases.
Out of the three connection technologies, push-to-connect is the easiest to install but oftentimes causes the most confusion.
Seven steps for expert installation
By following these simple steps, you will be an expert installer of Transair® push-to-connect fittings. (Full lengths of Transair pipe only require three installation steps, while cut lengths require seven steps.)
Installing full lengths of Transair aluminum pipe 1. Inspect the connectors for the proper torque settingEvery Transair connector comes pre-torqued from the factory. This is represented by solid and outlined arrows on the nuts aligned within a corresponding torque range on the body of the connector.

Today's state-of-the-art laboratory and medical instruments are smaller, more accurate and higher performing. Many applications, such as those in analytical chemistry (mass spectrometry and gas chromatography) and clinical diagnostics (laser therapy and hemodialysis) require extreme levels of performance. Instrument manufacturers require reliable, efficient, innovative components to stay competitive and meet the needs of new, demanding applications.
A component that has continued to evolve to meet the design needs of original equipment manufacturers (OEMs), is the solenoid valve. Solenoid valves are used in a variety of instruments to provide precision control in gas and liquid handling applications.
Here, we’ll review some of the capabilities a solenoid valve should deliver on to meet the needs of applications requiring extreme levels of performance, including:
Achieving a very low level of leak rate is quite challenging but can enable instrument manufacturers to simplify their designs by reducing the need for secondary positive shut-off valves in extremely low leak requirement applications. This can also be especially helpful in applications where the fluids being controlled are expensive and a leak could result in unexpected waste or in analytical chemistry applications where a leak would result in inaccuracies.
Many miniature valves have maximum operating temperatures in the range of 60-80°C; however, for today's demanding applications, it is important to choose a valve that can support high-temperature applications up to 105°C (221°F).
For applications that require a high pneumatic pressure capability, a valve with an orifice rated up to 86 bar (1,250 psi) is ideal. This allows manufacturers to use the valve in challenging, high-pressure applications, without having to consider expensive hydraulic valves as potential options.
Selecting a valve with a very strong solenoid helps provide a fast response time of <5msec. Rapid response time enables OEMs to provide a differentiated capability within their system. Faster response time can be especially useful in dispense applications where timing is used to estimate the volume of fluid being used in the application. For valves that have potentially long response times, the accuracy of using the total open time to help estimate the volume of fluid dispensed can be compromised.
The Series 9 solenoid valve, for analytical chemistry and clinical diagnostic applications, combines extreme pressures, tight leak specifications and wide temperature ranges with an unmatched compact size.
This miniature solenoid valve offers superior precision control in gas and liquid analysis. Combining high speed, ultra-low leak rate, high flow, and high-temperature capability in a small size, this durable valve operates with extreme repeatability and is constructed of non-corroding, passivated stainless steel.
Parker frequently refers to the Series 9 valve as our extreme performance valve. This is based on the extreme capabilities the valve can provide in terms of the very low leak rate, high-pressure and temperature range, and rapid response times. If your application requires these extreme levels of performance, the Series 9 valve may be an ideal solution to consider. In our next post, we will review some interesting applications in which the Series 9 valve provides significant value.

How OEMs Can Improve Life Science Instrumentation Performance
Our sense of taste is changing. We’re becoming more health conscious of the foods and beverages we consume to living a better life. No more perplexing and hard-to-pronounce food labels. Rather, simplicity rules the day as consumers seek transparency in knowing the ingredients going into the products they eat and drink. Simple does not discount sophistication though. The demand is present for high-quality foods that are healthy, sustainable and of course, appease the tastebuds.
So then, what does this all mean? Food and beverage companies have to think differently about infrastructure and plant operations to satisfy evolving appetites, from processed foods to healthier options. Manufacturing processes need to be structured to support plant-based foods and successfully manage fresh and short shelf-life products that do not contain artificial preservations or ingredients. This involves a fundamental shift in how food is produced, from shifting operating models to investing in new technology, to bring healthier, fresher foods and beverages to market.
The food manufacturing industry is highly competitive. In the United States alone, there are 27,000 organizations, generating annual revenue of nearly $790 billion. Being operational efficient to produce and distribute a complete, desirable and quality product while staying mindful of consumer tastes and nutritional trends ensures business longevity and its place among competitors.
This is no easy feat. There are many challenges and obstacles unique to the industry, including government guidance and regulations, food and beverage safety standards, extremely elaborate food processing machinery and sanitation equipment, and supply chain and logistical difficulties. In return, organizations may be reluctant to make changes and bring aboard new technologies, as this may be assumed as digital disruption, causing roadblocks in the form of production downtime and maintenance costs.
Improve product quality through condition monitoring
Adapting new technologies and processes will be a necessity for food and beverage. The integration of innovative applications, advanced equipment and better automation translates to an improved product (in regards to food taste and safety), an increase in productivity and efficiency, and reducing unscheduled machine downtime.
How can these initiatives be achieved while producing a superior product? The food and beverage manufacturing sector has the tendency to be late adapters of digital trends. However, the affordability of technologies coupled with improved software tools creates a compelling case for implementing the Internet of Things (IoT) solutions. And the course of action to establish sound machines is with condition monitoring.
Simply put, condition monitoring is the process of observing the parameter of conditions in machinery and equipment (temperature, pressure, humidity, vibration, etc.) in order to identify performance anomalies during operation. Over time, these indicators of equipment and system health will become easier to predict, allowing for the appropriate measures to resolving issues before escalating into serious complications and resulting in machine downtime.
Implementing a condition monitoring solutionCondition monitoring is achieved through sensors and software that is constantly capturing a variety of data points that can be utilized to monitor the health of an asset. For example, Parker’s SensoNODE™ Gold sensors and Voice of the Machine™ Cloud Software provide continuous condition monitoring of equipment. Together, they work in coherence to monitor temperature, humidity, pressure, current and vibration. These are critical parameters to measure in the food and beverage plants in establishing food safety.
SensoNODE Gold sensors can be attached anywhere on a machine, even in the most difficult-to-reach locations, transmitting real-time measurements to the Voice of the Machine Cloud web-based platform that allows viewing data 24/7 from anywhere with an internet connection. Workers can monitor asset conditions and changes among the different processes to identify abnormalities and resolve those issues through simple, wireless monitoring. This prevents unnecessary production downtime and costs associated with maintenance and repairs.
Voice of the Machine web-based solution presents data through easy-to-understand dashboards and provides notifications when measurement thresholds are exceeded. A user-friendly interface makes connecting sensors uncomplicated and measurements easy-to-read. Exporting of data is done with a click of one button, which sends a CSV file right to your email. The wealth of data collected can be leveraged to tweak existing processes, establish new systems, cut maintenance costs, increase product output, and utlimately increase the bottom line.
SensoNODE Gold Sensors and Voice of the Machine Software create a touch free experience, as up-to-date machine measurements are available to be viewed via an internet connection. Whether on the plant floor or out of the office, workers can monitor and analyze data from multiple assets and get alerts of deviations, which ensures continuous productivity, increased efficiency and eliminates downtime that improves the overall bottom line.
