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.

2000/03/31 · The rehabilitation of a leaking subsea check valve on an operating gas line operating at 1,160 psi was completed by Mexsub using a sleeve system to encase the valve. The repair, which was conducted in th of Campeche offshore Mexico, did not require shutting down the pipeline or reducing flow, or welding on the valve body.

Parker provides the industry's widest selection of check valves, available in a variety of end connections. Our valves are used in a diverse range of applications, from air and fuel systems to load holding. Our check valves utilize a variety of media including oil, air, and water and are made from materials such as aluminum, stainless steel, brass, and carbon steel. Parker check

Rated for up to twice the pressure of standard check valves, these can withstand pressures up to 3, 000 psi. High-Temperature Threaded Check Valves The heat -resistant rubber seal withstands temperatures up to 500° F.

WITT relief valves also stand out due to their high blow-off flow rates of up to 970m³/h. They can be used within a temperature range of -76° F to +518°F and even with very low pressures. These very low pressure valves can also be used in reverse, to maintain a constant gas pressure in a vessel, very accurately and very reliably.

09/28 · Higher pressure on the outlet causes the valve to close. A check valve, also known as a non-return or one-way valve, is a two-port safety device that allows gas, steam, or fluid to flow in a single direction. Its primary purpose is to restrict backflow in a system. There are a variety of check valve stopping mechanisms, including a disc, piston

High-quality gas non-return valves protect against dangerous gas backflow. Low opening pressure - leak-tight elastomere sealing system - long service life.

Duckbill Check Valve is duckbill non-return valve, one-way check valve, performing a vital function to prevent backflow. Flow control check valve will open to allow the flow of fluid, liquid, water, air and gas as the opening or cracking pressure increased. Silicone rubber duckbill valves are widely used as seal or nozzle for breast pump, drain, medical device application.

Description: from 2 to 40 psi. Like the Basic-Check® valve, the Restrictor Check provides reliable, low maintenance service for a wide range of fluids and gases at various pressure/temperature combinations. The valve consists of a guard cage, spring, valve disc, Connection: Threaded. Flow (Cv): 5.8 to 90. Material of Construction: Stainless Steel.
