Reliable cooling is a decisive factor for production, particularly in the marine industry. It is responsible for ensuring adequate temperatures in the turbine, the electronics racks and on the tool, or the machine, itself. The entire production and product life cycle of elements and machines are dependent on the efficiency of the cooling process and how it ensures ideal operating temperatures.
Parker has a broad program of thermal management components. It stands out thanks to its efficient interplay which is essential for ensuring that cooling circuits work reliably on a permanent basis. Each individual product stands for reliable functionality, durability, high material quality and compact design.Parker quick-action couplings are easy and fast to assemble
Quick-action couplings that can be used to connect cooling elements and cables are well suited to the thermal management field. Parker's RNS Series systems for block and panel installation expand the possibilities of design freedom for planning and installation. The series was initially developed for control cabinets to allow fast and reliable coupling and locking of the cooling circuits to the racks.
It has several benefits:
Another benefit of Parker's quick connection couplings is the variety of materials available. NSA Couplings, for instance, are made of aluminium and correspond with the trend towards lightweight construction. In addition, components made of nickel-plated brass or stainless steel are corrosion-free with a wide range of liquids, while offering consistent quality and long service life, just like the other couplings. Thanks to the different sizes available (3, 6, 9, 12, 16, 19 and 25 mm), couplings can be adapted optimally to the specific cooling circuit. When used in transportation systems, the couplings prove their resistance to vibration and torsional movements.Silicone hose minimizes maintenance costs and assembly time
The 6722 Series Silicone hose is an important system element for the heating and cooling applications as they allow to minimize maintenance cost and time and maximize the performance of the system.
The extruded hose meets SAE J20 R3 Class A specification and can be installed as thermal management solution wherever there is a cooling/heating circuit to run efficiently. The low permeation material is suitable for a wide range of coolant fluids and withstands ozone and UV attack more efficaciously than traditional solutions. The series is not only chemical and oxidation resistant but also extremely stable at elevated operating temperatures in engine compartments starting from –54°C to achieve +177°C. It maintains flexibility and elasticity over time. This reduces the risk to crack, harden, or become dry rotted and increases the possibility of installation in narrow and compact spaces, tight envelopes and around an obstruction. Additionally, it offers good ability to dampen sounds and vibrations keeping a quiet and stable profile. All these benefits contribute to an extended service life reducing costs of maintenance, downtime, warranty and logistics while sustaining the performance of circuits and equipment over the long haul.
There is no better choice for today’s trend where there are applications surpassing the temperature capabilities of other rubber solutions on the market. Silicone is the ultimate choice for extreme temperature applications and when flexibility over the lifetime is requested.Total system solution
The wide Parker product range for Thermal Management is enlarged by its extensive portfolio of push-to-connect fittings as an alternative to metal screw-on, clip-on and barbed connection technologies. The productivity is increased thanks to quick assembly (connection without tools; no need to weld, glue or crimp).
Based on its broad product range, Parker develops modular systems in close collaboration with its customers. In addition to individual products, the company also offers ready-to-install systems from coupling to screw fitting, hose or distributor. The benefit for the customers is that they can rely on the supplier’s decades of experience and they can save valuable assembly time thanks to the delivery of complete systems blocks, which in turn greatly simplifies the spare parts stocking process.

ISO 14001: was recently updated to ISO 14001: 2015, which introduces a few requirements to a universally beneficial certification. Key benefits of ISO 14001: 2015 include:
Reducing environmental impact
When becoming ISO 14001:2015 certified, Precision Fluidics Division of Parker Hannifin was getting two trash and one recycling pickup each week. The goal was to reverse those numbers. It was achieved in 18 months by training, raising awareness to all employees, increasing recycling bins throughout the facility with signs/labeling, and constant monitoring. Goals of this magnitude take time and planning, but the environmental rewards are immense.
Helping our customers and our team
Precision Fluidics is a great example of an organization set on reducing its environmental impact. A goal was set to improve the durability of product packaging and eliminate landfill waste at a customer location by introducing recyclable materials. A few simple adjustments were made such as using recyclable trays instead of bubble wrap, bubble bags, and foam inside each shipping container. The change resulted in energy savings, trash reduction, and reduction in the weight production needed of each box. The total result was almost 64,000 pieces of foam a year eliminated from landfill, 100% percent recyclable packaging, and a simpler tray packaging system.
Transitioning to a tray system reduced the weight the production team needs to handle when transporting from the production cell to shipping, providing a much-appreciated safety and ergonomic improvement. Another exciting feature of the new packaging is that our product is even more secure during shipment. Following the ISTA (International Safe Transit Association) test procedure, Precision Fluidics validated the new packaging to be an improvement over the non-recycled foam — reducing the risk of shipping damage and increasing the product quality when it's received at our customers' locations.
Reduce, reuse and recycle
Another simple adjustment Precision Fluidics has made is utilizing reusable packaging for component parts from repeat vendors.
Precision Fluidics reuses trays from various vendors when possible (see image left). After the trays are empty, they are shipped back to the vendor and reused. This is a great example of a very simple way to reduce, reuse and recycle.
Precision Fluidics is an ISO 14001: 2015 certified company that has set both large and small goals that have been beneficial to the company as a whole, customers, and best of all, the environment. The above examples show how ambitious yet simple goals can have great impacts. The main objective in ISO-14001: 2015 is having continuous improvement and never being content with what you have achieved.
The first step in becoming ISO 14001:2015 certified is to define your objective. What does your company want to achieve by getting this certification? Make sure you have the support of senior management. Take the time to review any existing processes and systems pertinent to environmental impact. If desired, third-party certifications are available that will conduct audits of your practices against the requirements standards. ISO does not perform certification.

One of the most import medical devices created in the last century is the ventilator. The ventilator is critical for patients who cannot breathe on their own due to medical procedures or long-term respiratory ailments. The significant impact the ventilator has had on the medical industry has made the device an essential piece of emergency care, intensive care, and anesthesia delivery.
Ventilator technology is rapidly advancing, and OEMs (original equipment manufacturers) need component manufacturers to design innovative new parts to meet their demands. Here, we’ll examine what OEMs are looking for when it comes to one of the most crucial components of ventilators — proportional control valves.
From a design standpoint, ventilators can be complex and costly. Using versatile parts that have multiple functions/settings allows OEMs to reduce part complexity — decreasing the number of vendors required as well as making the device easier to manufacture and repair. A proportional control valve that features a wide linear control range makes it possible to have a single ventilator for various desired flow ranges. For instance, different flows are required for a child vs. an adult in respirators or anesthesia delivery.
Other features OEMs are looking for in a proportional valve for the next generation of ventilators are fast response time and consistent flow from cycle to cycle. Fast response is necessary to deliver oxygen in milliseconds when sensors detect a patient trying to breathe. Smooth, consistent flow is very important for the patient’s comfort and safety.
Lastly, OEMs want valves that are compact and energy-efficient. Power and space are limited in portable ventilators. Emergency ventilators need to be light and easy to maneuver. When a hospital loses power, ventilators continue to operate on emergency power and batteries, so any power reductions in the ventilator’s design are desirable.
A one-size-fits-all valve solution
The valve that is meeting all these demands is Parker’s new LM-Pro (Linear Motor Proportional Valve) — an innovative miniature proportional valve that is separating Parker from the competition. The LM-Pro introduces unparalleled flow control capabilities to meet OEM needs. Featuring a linear controllable flow range from 0.5 to 540 slpm for precise flow control, the LM-Pro ensures the accurate and safe delivery of precise gas flow to patients, from neonates to adults. Additionally, this valve offers a pressure capability up to 100PSI (6.9 Bar), and typical power consumption of fewer than 2 watts. It has been tested to well over 100 million cycles. With all these advancements, the LM-Pro is still easily face-mounted/ported into ventilator systems and can be configured with an optional inlet filter to prevent debris from dirty system connections from entering the valve. Parker’s LM-Pro is the only valve that’s meeting OEM demands to make the one-size-fits-all valve solution to achieve the next level of ventilator technology.
LM-Pro typical airflow with 12 VDC Coil
The LM-Pro dimension
The LM-Pro is lightweight at 36.6 grams (1.29 oz) and sized for all OEM applications. Read more technical specifications of this product here.
International Standard Organization (ISO) certifications
In addition to the LM-Pro breaking ground with its broad range of controllability, pressure capability, low power consumptions, and validated to over 100 million cycles; this proportional valve has been carefully crafted to comply with some of the most sought-after certifications for medical components. The LM-Pro is certified in two critical ISO standards for anesthesia and respiratory applications: ISO 10993:2010 and ISO 15001:2010. ISO 10993:2010 certification means this valve is biocompatible and does not use materials that can potentially cause irritation when used in breathing circuits. ISO 15001:2010 certification means this proportional valve meets the cleanliness requirements for oxygen circuits. The LM-Pro is compliant with RoHs directive (2002/95/EC) and Reach EC 1907/2006, which means this valve doesn’t use any hazardous materials that can’t be recycled and is composed of registered, evaluated and authorized materials. The LM-Pro is meeting new market needs and complying with the most important medical device certifications.
The ventilator is an essential piece in emergency care, intensive care, and anesthesia delivery, and will continue to be a pivotal part of health care as it adapts to our needs, whether portable, lower power consumption or multiple flow control settings. As ventilator technology advances, OEMs will require innovative products like the LM-Pro miniature proportional valve to stay competitive in the ever-changing medical device market.

Ball valves are used in a variety of industries such as manufacturing, oil, and gas, automotive, marine, agricultural and heavy truck. Applications may vary but include operations for processing, transferring, pneumatic circuits, cooling, and measuring such as
• Fuel line shutoffs for gasoline and diesel equipment
• Air service lines
• Water service lines on capital equipment
• Plant design plumbing requiring total shutoff capability
To select the right type of valve for your application, it helps to understand what a ball valve is and the differences between the key types: full port or standard port ball valves.
The full port valve design
A full port or sometimes called full bore, ball valve has a straight flow path where there is not a reduction of flow as it travels through the valve. In other words, the internal diameter of the pipe or tubing at the inlet and outlet of the valve has the same diameter as the interior of the ball valve. The diameter remains constant and does not narrow as it passes through the valve.
The standard port valve design
A standard port also has a straight flow path, but there is a flow restriction that produces a pressure drop as the flow passes through the valve. Basically, the valve inlet and outlet connections are the same sizes as the tubing or pipe, but the interior component (the ball), which fits within the valve, has a smaller bore (hole) than the pipe or tube that it is connected to, therefore producing the pressure drop due to the flow restriction.
How do you determine if you need a full port ball valve or if a standard port will suffice?
Some applications require a full port ball valve due to a characteristic of their application; for example, if low flow resistance is needed. In the case of a pump suction pipe where a pressure drop can impact the performance of a pump, a full port valve may be the best choice to maintain flow.
Yet, unless your application requires a full port, the standard port is the default valve for most functions. It provides the most cost-effective way to control the flow in many applications. Concurrently, where so often space constraints are an issue, their relatively compact design gets the job done with a smaller ball valve body, so long as a pressure drop or flow turbulence is acceptable in your system.
Parker's V525P industrial ball valve solution
Parker Fluid System Connectors Division offers a wide range of industrial standard port ball valves in a variety of materials, configurations, and handle options to meet your application needs. Our new V525P standard port ball valve offers the superior quality of a Parker industrial ball valve that you are accustomed to, and a cost-effective solution when a full port valve is not necessary.
Parker offers the widest range of brass fittings and valves. From extruded, forged, plated, and composite materials, we make connections to bring increased efficiencies and higher productivity.
Choosing industrial versus commercial
A final note on choosing industrial and commercial ball valves. Your best choice should be designed and manufactured to provide years of service at an economical price. Ultimately, those valves will deliver increased performance over any lightweight throwaway valves.

Formed hose and hose/tube assemblies have long been used to solve fluid handling system design challenges such as installation in confined areas or those necessitating a tight bend radius. While both approaches have specific benefits—ease of replacement for formed hose and smaller allowable minimum bend radius for tube assemblies—they also introduce some potentially costly drawbacks:
When combined with the other environmental and usage factors that can adversely affect hose performance and life expectancy, it’s clear that better solutions are needed to improve hose performance while avoiding costly downtime and system repair.
Issues affecting hose performance
While hoses have a finite lifespan under normal conditions, it is helpful to understand that their service life can be adversely affected by a variety of factors.
These factors include:
“Fluids are the lifeblood of industrial and mobile equipment, and as conduits for these fluids, hose assemblies are critical to system performance.”
Jeff Grau, engineering manager, innovation, Parker’s Hose Products Division
The frequency of the occurrence of many of these issues has been increasing due to continuing end-product evolution that has generally reduced available space and increased the ambient temperature within that space.
Three key hose-related equipment requirements
Recognizing that the market needed a safer, more reliable and cost-efficient alternative to formed hose and hose/tube assembies, Parker developed the E-Z Form hose series: a system-based solution to challenging application problems. This provides a single-source reliable solution that meets all requirements effectively and economically. These are the requirements we focused on:
Requirement #1: Withstand extreme bends and tight routing without kinking
Requirement #2: Reduce potential for leaks in assemblies with multiple connections
Requirement #3: Eliminate the need for extensive and costly replacement inventory and related replacement time

Air conditioning lines are one of the most critical components in an A/C system. They work as the central hub to deliver both gas and liquid refrigerant throughout the system. For a variety of reasons, A/C lines can fail over time causing costly replacements and lengthy lead-times for the end user. All vehicles can experience some leakage through seals and hose crimps, but as vehicles age, seepage increases. Repairing leaks is crucial since low refrigerant fluid levels prevent an A/C system's compressor from turning on.
Leaks can be easily detected by spraying hoses and couplings with soapy water and using the bubbles to pinpoint leaks. Often end-users are faced with the challenge of needing a high-quality replacement part that can be assembled quickly in the field. They may need a product which solves difficult applications like tight routings, or one that eliminates the need for crimping machines and dies which may be unavailable on site.Parker's solution
Parker's A/C Clip stands out in quality, value and performance in even the most demanding applications of R134a and R1234yf air conditioning and refrigeration systems worldwide. The design is simple and only requires readily available hand tools. Parker also offers a comprehensive line of A/C style end connections available to meet the needs of many different applications.
This innovative product meets SAE J2064 standard and provides an end-to-end solution with Parker’s 285 Refrigeration hose. The hose/fitting combination guarantees the lowest possible refrigerant permeation along with superior hose flexibility as compared to existing products in the market.Assemble in six simple steps
For the A/C clip installation guide, you will need the following to get started: hose, hose cutter
Step 1: Cut hose to proper length with hose cutter
Step 2: Place two A/C clips on the A/C clip chamber
STEP 3: Slip assembled A/C Clip Chamber with A/C Clips onto the hose until the closed end of the Chamber contacts the end of the hose.
STEP 4: Replacement of Air Conditioning Hoses Made Simple Step 3 Hose Products Division
STEP 5: Insert fitting until the hex contacts the hose end with the A/C Clip Chamber.
STEP 6: Tighten A/C Clips with the pliers until the ear clamp ends make contact or meet. Expect a slight “spring back” or gap once the pliers are released. If you are using pneumatic pliers (Optional) to close the A/C Clips, the pliers open themselves when the correct closing force has been reached.
Parker’s Hose Products Division delivers unparalleled quality and reliability in products engineered for the success of your application. Learn more here about the innovative A/C Clip.

Representing up to 40% of the electricity consumed by a company, compressed air is a fluid with many challenges. Poor management of this fluid and/or the design of its distribution network results in significant additional costs, but also low availability with negative consequences on production.
One of the challenges for industrial fluid networks is to integrate into a new industrial dimension of total automation for optimal productivity.
The compressed air network becomes an interconnected system in its industrial environment.The means for the designer to achieve optimal productivity:
Each compressed air network is unique, as user needs are variable, and the configuration possibilities are large. The main priorities for their operation are focused on the qualities intrinsic to the design of the compressed air network.
In a fully automated environment, other areas of improvement are made available for greater productivity:
Flexible and modular production methods and therefore completely reconfigurable.
Analysis of information, cloud, production line performance.
The implementation of means to ensure predictive maintenance.
Efficient monitoring of energy consumption and raw materials.
The use of virtual means for process simulation.
The integration of the Internet of Things into manufactured products.
It, therefore, becomes essential for an installation to interact with its environment.
What monitoring brings to the user and designer:
All companies try to keep downtime to a minimum. The best tool for this is preventive maintenance. It consists of shutting down the installations according to plans, performing scheduled maintenance and restarting without complications.
Preventive maintenance systems (condition monitoring) are based on value history, which originates from the phase of correct operation of the machines. Real-time measurement of values ensures that they are as close as possible to any variations and can be analysed as soon as they appear in order to refine the maintenance plan, create alerts or intervene in real time.
Moreover, having this information available in a given environment allows the designer to make changes to the system so that it can be even more adapted.
Monitoring will ensure greater responsiveness and understanding of processes and systems at two levels. That of the users and that of the designers. Monitoring is optimally integrated into the continuous improvement plan within and outside the company and can become a tool for interconnectivity between companies.
Parker Transair's proposal:
Parker Transair brings to its customers a new evolution in the field of compressed air networks with its condition monitoring technology, which allows end-users to monitor their compressed air network systems and maintain their productivity, anywhere and anytime.
The Transair Condition Monitoring System (TCMS™) uses wireless sensor technology to monitor the compressed air piping system, alert the end-user to system changes and provide critical data that helps reduce downtime and increase productivity.
A user-friendly web interface allows users to easily view and analyse the data to ensure that the system is operating at optimal levels of pressure, power, temperature, humidity and flow.
A 4-20mA wireless transmitter allows other equipment to be connected to the system to make their data available at the interface.
Transair Condition Monitoring System (TCMS™) helps to reduce overall costs by avoiding unnecessary downtime and extending the life of sensitive equipment.
"It is essential for end-users to be able to accurately monitor this data, because compressed air systems are very complex and highly scalable."
Guillaume Tetard, Director of the Transair Business Unit.
Transair Condition Monitoring System (TCMS™) complements the Parker Transair Aluminum Network System, known for its high performance, corrosion resistance and efficient use in a wide range of industries.
"Thanks to the light weight of Transair components and the instant connection technology, manpower is reduced to only 20% of overall installation costs, which saves money right from the start."
Françoise Lunel, Transair Communication Manager.
Combining a Transair system with the Transair Condition Monitoring System (TCMS™) will save the company money by finding ways to increase air supply efficiency, reduce maintenance costs and prevent unwanted scrap, thereby reducing the overall cost of the plant.

When selecting the right coupling, the frequency of hose connection and disconnection is a major factor in the type of coupler that should be used. For example, at workstations where pneumatic tools are being changed many times throughout a shift, a quick connect coupler allows rapid tool replacement and provides a significant increase in productivity.
Another example is hydraulic testing processes. Quick couplings significantly reduce the time required to test each assembly. If technicians were required to tap into systems using a wrench to connect and disconnect, valuable time would be added to each testing procedure. Again, productivity increases with the use of quick couplings.
Many industries are rapidly adopting quick couplings for this very reason, realizing the increase in efficiency far outweighs the increased costs.What is a quick coupling?
A quick coupling, often referred to as a quick coupler, QD or quick-acting coupling, is a mechanical device that provides a fast, easy, sure way to repeatedly connect and disconnect almost any fluid or gas line. All quick-connect couplings have two parts: a plug and a socket. The plug is the male half and the socket is the female half. When connected properly, these parts seal and lock the joint effectively to contain internal pressures and resist any tensile forces that tend to pull the joint apart.
The most significant advantages of a quick couplings over standard hydraulic connections are:
Time of connection/disconnection
Prevention of fluid leakage
Cost is a factor that prevents quick connect couplings from being more widely used. These couplings contain many more components such as valving and locking mechanisms, which means higher material and assembly costs.
Secondly, there is an issue of pressure drop. Media flowing over the internal valves causes turbulence in the media - either fluid or gas. Think of the effect rocks have on the flow of a river. This can cause a slight drop in pressure that can be measured as ‘pressure drop’ (PSID).
Choosing the right coupler for the job
Before selecting a coupling, important questions must be answered regarding performance:
Once these questions have been answered, a preliminary selection of coupling type can be made: one, two or no shutoff valves, and the type of connect and disconnect mechanism. Keep in mind that one style may offer the greatest convenience in service, but a different model's lower pressure drop may be more desirable for the application.Single shut-off couplings
Single shut-off couplings are primarily used for pneumatic or gas applications, connecting air tools, hoses or other implements to compressed air and gas supplies. In these applications, the coupler half (female) is valved while the nipple half (male) is un-valved or “straight-through.” Upon inserting the nipple, it opens the valving on the coupler, which allows flow. When disconnecting the nipple, the valve on the coupler automatically closes which stops flow from the coupler.Double shut-off couplings
Both coupling halves are frequently valved in the case of hydraulic applications. Double shut-off couplings minimize fluid leakage while limiting the amount of air, dirt and water that can become trapped between valves during reconnection. To address these concerns, many manufacturers offer flat-faced couplings that reduce fluid spillage to a drop or less every time the coupling is disconnected.Parker solutions
The impact of employing quick connect couplings will make a difference in any operation where reliability, time and productivity are of the utmost importance. Parker’s Quick Coupling Division is the largest quick coupling manufacturer in the world, providing quick disconnects and accessories that are appropriate for use in countless applications across widespread markets where fluid lines are connected and disconnected. These markets include aerospace, subsea gas and oil exploration, agriculture, electromechanical, filtration, thermal management and all others that require reliable, safe connections.
Many of Parker’s coupling products are available with unique non-standard options well suited to very specific applications. Examples of unusual end-use applications might include: high temperatures (above 250° F), extremely caustic/corrosive solutions passing through the coupling, external/environmental corrosion situations or other high wear and tear situations such as dragging the product along the ground.Learn more about Parker’s Quick Couplings.
