They are also used to isolate compressor packages from system piping, and throughout distributed system piping itself. As with most piping systems, keeping pressure drops and turbulence low is important. ## Compressed Air System Valves ![Compressed Air Check Valve](https://www.usvalve.com/assets/internal-buckets/compressed-air-systems.jpg)![Pneumatic Valves - Check & Ball](https://www.usvalve.com/assets/content-images/Valves/Flanged%20Check%20Valves/Flanged%20Elastomer%20Illustration.png)![Compressed Air Ball Valve](https://www.usvalve.com/assets/content-images/Valves/Industrial%20BALL%20Valves/IMG_6795-640px.jpg) ## Pneumatic Check Valves Full Port Pneumatic Check Valves are manufactured to provide more flow and lower pressure drops than conventional check valves. Our elastomer hinge check valve design takes performance to an entirely new level by eliminating the restrictive valve seat and substantially increasing the valve’s open area and flow coefficient (Cv). ## Pneumatic Ball Valves Our Full Port Pneumatic Ball Valves are manufactured to offer open flow paths, thus reducing turbulence and noise. They are ideal for application in vacuum pumps, compressed air and gas systems as well as in water systems where low head loss and elimination of water hammer are desirable. ### Fast Delivery of Pneumatic Check Valves We maintain an extensive inventory of  pneumatic ball valves, parts and components in a wide variety of materials so we can respond to your needs quickly. Valves are typically assembled and tested within 1 to 2 days after receipt of an order. ### Compressed Air Valve Features & Benefits Our Pneumatic Check Valves offer some impressive advantages over competitive designs. - **Lowest Pressure Drop in the Industry** - **Available in 316 SS, Carbon Steel, Cast Iron, Brass, Aluminum** - **Most Carbon Steel Valves include Zinc DiChromate Plating** - **Male & Female NPT, Wafer, Grooved & Plain End, API, etc** - **Easy to Install, Quiet Operation** - **USA Content, ARRA Compliant** - **Our Check Valves Alleviate Water Hammer** - **Every Valve is Tested Prior to Shipment** ### Complete Engineering Data for Pneumatic Check Valves Engineering data, including available materials, dimensions, exploded view, part numbers and descriptions, standard models, valve Cv, pressure loss curves, and other information on these pneumatic check valves is available in our brochures.

Our elastomer hinge check valve design takes performance to an entirely new level by eliminating the restrictive valve seat and substantially increasing the valve’s open area and flow coefficient (Cv). Our Full Port Ball Valves offer open flow paths, thus reducing turbulence and noise which makes them great fire fighting valves. They are ideal for application in vacuum pumps, compressed air and gas systems as well as in water systems where low head loss and elimination of water hammer are desirable. ### Fast Delivery We maintain an extensive inventory of fire fighting valves, parts and components in a wide variety of materials so we can respond to your needs quickly. Valves are typically assembled and tested within 1 to 2 days after receipt of an order. ### Features & Benefits of CAFS Systems Our Fire Fighting Valves offer some impressive advantages over competitive designs. - **Lowest Pressure Drop in the Industry** - **Available in 316 SS, Carbon Steel, Cast Iron, Brass, Aluminum** - **Most Carbon Steel Valves include Zinc DiChromate Plating** - **Male & Female NPT, Wafer, Grooved & Plain End, API, etc** - **Easy to Install, Quiet Operation** - **USA Content, ARRA Compliant** - **Our Check Valves Alleviate Water Hammer** - **Every Valve is Tested Prior to Shipment** ### Complete Engineering Data Engineering data, including available materials, dimensions, exploded view, part numbers and descriptions, standard models, valve Cv, pressure loss curves, and other information for our CAFS systems is available in our brochures.

US Valve Check Valves, Full Port Ball Valves, Vacuum & Pressure Relief Valves, and Breather Valves are used across a wide spectrum of Industrial Applications. They are also used to isolate equipment from system piping and throughout the piping system itself. As always, keeping pressure drops and turbulence low is important, but it is absolutely essential in Vacuum and Low Pressure systems, where available head is limited. We will also build custom actuated and non-actuated valves to meet your design specifications. ![Industrial Applications](https://www.usvalve.com/assets/home-buckets/check-valves.jpg)![Flanged Elastomer Check Valve Illustration](https://www.usvalve.com/assets/content-images/Valves/Flanged%20Check%20Valves/Flanged%20Elastomer%20Illustration.png)![Full Port Ball Valve](https://www.usvalve.com/assets/content-images/Valves/Industrial%20BALL%20Valves/IMG_6795-640px.jpg) ### Full Port, Lowest Pressure Drop Full Port Check Valves provide more flow and lower pressure drops than conventional check valves. Our elastomer hinge check valve design takes performance to an entirely new level by eliminating the restrictive valve seat and substantially increasing the valve’s open area and flow coefficient (Cv). Our Full Port Ball Valves offer open flow paths, thus reducing turbulence and noise. They are ideal for application in vacuum pumps, compressed air and gas systems as well as in water systems where low head loss and elimination of water hammer are desirable. ### Fast Delivery of Breather Valves We maintain an extensive inventory of breather valves, parts and components in a wide variety of materials so we can respond to your needs quickly.

For vertical down-flow applications, we typically recommend the addition of a spring. ## What is the cracking pressure for these valves?View More The cracking pressure of a check valve depends upon the spring that is selected. A typical value for a standard spring is 0.2 PSI, while a typical light spring would have a cracking pressure of about 0.1 PSI. Lighter and Heavier Springs are available. Full port check valves are supplied without springs for many applications, eliminating the cracking pressure entirely. Check with our application engineering department to discuss your particular application and to get exacting specifications for the valve used for you application. ## How do I know if an internal spring is required for your check valves?View More Internal Springs are required for ANSI style dual plate wafer check valves, as well as for most check valves installed on liquid applications. Full port check valves can and often are installed without springs. We do recommend using a spring for vertical down-flow, all liquid applications, and for low flow air or gas applications. ## Do you build Custom Valves and Specials?View More Yes, we often build custom valves to customers' specifications. Please [Contact Us](https://www.usvalve.com/contact-us) by phone or email to discuss your exact requirements. You can also use "Request a Quote" or "Have a Question?" forms on the right side of our web page. ## Where can I download your Brochures and Technical Data?View More Most of our individual Valve web pages include links at the bottom of the page to download the corresponding product brochure. These brochures include a wealth of technical information about our products, including material specifications, dimensions, performance curves, pressure ratings, etc. You can also download files directly from our [Engineering Resources](https://www.usvalve.com/engineering-resources) page, which lists ALL the files currently available. Brochures are in PDF format. ## Do you offer Oxygen Cleaning?View More YES...All our Medical Gas ball and check valves are oxygen cleaned per CGA G-4.1. They are then capped and packaged in a polyethylene bag to keep them clean. If you require oxygen cleaning for non-Medical Gas valves and/or applications, please contact us for information. ## Do you Test your valves?View More Yes. All our valves are tested before shipment. Our ANSI/API Dual Plate Wafer Check Valves are tested in accordance with API 598. Full port check valve seats are tested using low pressure air to assure that they seal for all applications. Ball valves are tested according to MSS-SP110. ## What is the difference between a Full Port Wafer check Valve and an ANSI Dual Plate Wafer Check Valve?View More A Full Port wafer check valve uses an elastomer hinge as its sealing mechanism, which eliminates the need for any restrictive seat in the check valve. This means that the Full Port wafer check valve will have a lower pressure drop and a higher Cv than an ANSI Dual Plate wafer check valve. The ANSI Dual Plate wafer check valve is designed in accordance with API594 and is therefore often used for many process applications where reliance on known standards is the norm. ## Do you accept credit card payments?View More We accept VISA, MasterCard and American Express.

Operation is similar to a [ball valve](https://www.usvalve.com/ball-valves) in that it takes just one-quarter turn of the handle from fail open to fail close. A plate or disc is in the center of the pipe and has a shaft passing through it that is connected to a ten-position lever handle, gear-operated handwheel, or an [actuator](https://www.usvalve.com/butterfly-valve-accessories) on the outside of the valve. Rotating the handle turns the disc either parallel or perpendicular to the flow. The disc is always present within the flow; thus, some pressure drop is always induced in the flow, regardless of valve position.

We are known for our unique Elastomer Design, which provides the lowest pressure drop and highest Cv in the industry. This design is available on all our Full Port check valves. [ANSI dual plate wafer check valves](https://www.usvalve.com/ansi-dual-plate-wafer-check-valves), (which conform to ANSI / API specifications), are the only check valves that do not come with our low ∆P elastomer design. These valves are suitable for any orientation including vertical up flow and downflow. our check valves are certified to meet the requirement of NSF 61 and NSF 372. [Contact us](https://www.usvalve.com/contact-us) today to learn more about the different types of [NSF Certified](https://www.usvalve.com/nsf-certificates) check valves we have to offer. #### What is a check valve used for? A check valve is a one-way valve that prevents backflow. #### When should check valves be used? When two or more pumps or blowers are installed in parallel, check valves are used to isolate the ones that are not operating. In some applications, backflow is detrimental to the process or to equipment and must be prevented. #### How do check valves work? Check valves have a mechanism either spring-loaded or not spring-loaded whereby the valve automatically closes once the flow through it is reduced below a minimum amount.  When the flow increases again with stronger force, the valve will re-open and the media is once again able to pass through. #### What are the types of check valves? There are a wide variety of check valves including elastomer hinge, double-disc, piston, and ball check valves. They usually are available in various body types including FNPT, MNPT, Flanged, Wafer, and Grooved End. ### Materials - [Elastomers](https://www.usvalve.com/butterfly-check-valves-elastomer-hinged) - [Carbon Steel Valves](https://www.usvalve.com/carbon-steel-valves) - [Stainless Valves](https://www.usvalve.com/stainless-steel-valves) - [Brass Valves](https://www.usvalve.com/brass-valves) - [Aluminum Valves](https://www.usvalve.com/aluminum-valves) - [Cast Iron Valves](https://www.usvalve.com/cast-iron-valves) ### Markets - [Hospitals](https://www.usvalve.com/medical-gas-valves) - [Vacuum Pumps & Blowers](https://www.usvalve.com/vacuum-pumps-blower-valves) - Compressed Air Systems - [Water & Waste Water Treatment](https://www.usvalve.com/waste-water-treatment-valves) - [Power Generation](https://www.usvalve.com/power-plant-valves) - Industrial Applications - Firefighting Applications - [Well Applications](https://www.usvalve.com/heavy-duty-deep-well-check-valves) - [Data Centers](https://www.usvalve.com/data-centers) Click on the valve categories below to learn more.

Our facilities are kept neat, clean, and organized, with attention to detail that makes a difference in the quality of ANSI dual plate valves manufacturing. [Request A Quote](https://www.usvalve.com/request-a-quote "Request A Quote") ### Features & Benefits of Dual Plate Check Valves - **Exceeds API Specifications** - **Low-Pressure Drop** - **Light Weight** - **Lower Cost** - **Alleviates Water Hammer** - **Simple Installation** - **Every Valve Tested** - **Optional Retainerless Design** ### **Standard vs. Retainerless Body Designs** As a leading API 594 dual plate check valve manufacturer, our Dual Plate Wafer Check Valves are available in two different body styles—Standard and Retainerless. Both versions have the same performance, dimensions, and ratings. In all dual plate check valves, the center pin (off which the discs rotate) and the limiter bar (which prevents the discs from hitting each other) need to be affixed to the valve body. In a standard body style, the result is a penetration through the body wall. In a retainerless design, a sleeve is inserted into the inside of the body, thus avoiding penetrating the body wall. This makes retainerless style valves particularly desirable and applicable for critical Hydrocarbon and Chemical processing applications, or any service where environmental safety or fire hazards are concerned. ### The Industry Standard Dual Plate Wafer Non-Return Valves (equivalents of **Techno™ Check Valve 5050, 5051, & 5053**) were originally introduced in the late 1950s and quickly became the check valves of choice for many piping engineers because of their proven reliability and low-pressure drops. They have become the standard for process and project engineers worldwide and are used extensively in many different industries listed below. **Industries** - [Power Plants](https://www.usvalve.com/power-plant-valves) - Refineries - Chemical Plants - [Wastewater Treatment Plants](https://www.usvalve.com/waste-water-treatment-valves) - Pulp & Paper Mills. Our ANSI dual plate check valves conform to all industry standards. API 594 dual plate check valves dictate valve dimensions, including wall thickness, face-to-face dimensions, and OD, so valves can replace any make of ANSI Dual Plate Water Check Valve. ### Fast Delivery of Dual Plate Wafer Check Valves We are a API 594 & 598 dual plate check valve manufacturer that maintains an extensive inventory of valves, parts, and components in a wide variety of materials so we can respond to your needs quickly.

CTA: [Contact Us](https://www.usvalve.com/contact-us) ## Frequently Asked Questions About Data Center Valves ### What valves are used in a Coolant Distribution Unit (CDU)? Check valves are typically used at the discharge of pumps within a CDU to boost liquid coolant to servers. Elastomer hinge check valves are preferred because they enhance cooling efficiency, support higher power densities, reduce noise, improve energy efficiency, allow for expansion, and contribute to sustainability. ### What is the most efficient valve to use in a data center liquid cooling? Elastomer hinge check valves are the most efficient for data center liquid cooling systems because they minimize pressure drops while maintaining peak efficiency. Compared to globe or poppet valves, elastomer hinge check valves allow nearly double the coolant flow using the same pumps. ### How can you reduce pumping costs in data center direct-to-chip cooling? Install an elastomer hinge check valve at the discharge of the liquid pump to reduce pumping costs. This design increases coolant flow with significantly less pressure drop, resulting in energy savings and optimal cooling performance. ### How do you protect a coolant pump in a data center? The most effective way to protect a coolant pump in a data center is to install an elastomer hinge check valve. These valves prevent backflow, maintain consistent pressure, and ensure reliable cooling, protecting the pump from damage. **Complete Engineering Data** [View Flyer](https://www.usvalve.com/pdf_view/Data%20Center%20Flyer.pdf "View Our Flyer") [View Brochure](https://www.usvalve.com/pdf_view/Newpdfs/MNPT%20Brochure-2301010-0623.pdf "View Our Brochure") [Contact us](https://www.usvalve.com/contact-us) today to learn more about our data center cooling system valves or request a quote.

A check valve is a one-way valve that prevents backflow. #### When should check valves be used? When two or more pumps or blowers are installed in parallel, check valves are used to isolate the ones that are not operating. In some applications, backflow is detrimental to the process or to equipment and must be prevented. #### How do check valves work? Check valves have a mechanism either spring-loaded or not spring-loaded whereby the valve automatically closes once the flow through it is reduced below a minimum amount.  When the flow increases again with stronger force, the valve will re-open and the media is once again able to pass through. #### What are the types of check valves? There are a wide variety of check valves including elastomer hinge, double-disc, piston, and ball check valves. They usually are available in various body types including FNPT, MNPT, Flanged, Wafer, and Grooved End. ### Materials - [Elastomers](https://www.usvalve.com/butterfly-check-valves-elastomer-hinged) - [Carbon Steel Valves](https://www.usvalve.com/carbon-steel-valves) - [Stainless Valves](https://www.usvalve.com/stainless-steel-valves) - [Brass Valves](https://www.usvalve.com/brass-valves) - [Aluminum Valves](https://www.usvalve.com/aluminum-valves) - [Cast Iron Valves](https://www.usvalve.com/cast-iron-valves) ### Markets - [Hospitals](https://www.usvalve.com/medical-gas-valves) - [Vacuum Pumps & Blowers](https://www.usvalve.com/vacuum-pumps-blower-valves) - Compressed Air Systems - [Water & Waste Water Treatment](https://www.usvalve.com/waste-water-treatment-valves) - [Power Generation](https://www.usvalve.com/power-plant-valves) - Industrial Applications - Firefighting Applications - [Well Applications](https://www.usvalve.com/heavy-duty-deep-well-check-valves) - [Data Centers](https://www.usvalve.com/data-centers) Click on the valve categories below to learn more.

They usually are available in various body types including FNPT, MNPT, Flanged, Wafer, and Grooved End. ### Materials - [Elastomers](https://www.usvalve.com/butterfly-check-valves-elastomer-hinged) - [Carbon Steel Valves](https://www.usvalve.com/carbon-steel-valves) - [Stainless Valves](https://www.usvalve.com/stainless-steel-valves) - [Brass Valves](https://www.usvalve.com/brass-valves) - [Aluminum Valves](https://www.usvalve.com/aluminum-valves) - [Cast Iron Valves](https://www.usvalve.com/cast-iron-valves) ### Markets - [Hospitals](https://www.usvalve.com/medical-gas-valves) - [Vacuum Pumps & Blowers](https://www.usvalve.com/vacuum-pumps-blower-valves) - Compressed Air Systems - [Water & Waste Water Treatment](https://www.usvalve.com/waste-water-treatment-valves) - [Power Generation](https://www.usvalve.com/power-plant-valves) - Industrial Applications - Firefighting Applications - [Well Applications](https://www.usvalve.com/heavy-duty-deep-well-check-valves) - [Data Centers](https://www.usvalve.com/data-centers) Click on the valve categories below to learn more.

A check valve is a one-way valve that prevents backflow. #### When should check valves be used? When two or more pumps or blowers are installed in parallel, check valves are used to isolate the ones that are not operating. In some applications, backflow is detrimental to the process or to equipment and must be prevented. #### How do check valves work? Check valves have a mechanism either spring-loaded or not spring-loaded whereby the valve automatically closes once the flow through it is reduced below a minimum amount.  When the flow increases again with stronger force, the valve will re-open and the media is once again able to pass through. #### What are the types of check valves?
