Pascal Industries’ o-ring check valves offers reliable one way fluid flow control. O-Ring type check valves are used where tight shut off for liquids and gases are required. When the differential pressure drops below the cracking pressure, the valve shuts off.
316 Stainless Steel construction
Standard O-Rings include Buna-N (NBR), Viton, Teflon and Kalrez for a variety of applications. Other O-Ring materials are available upon request.
Standard cracking pressure is 20 psi (1.38 bar) ± 20%. Other cracking pressures are available upon request. Higher accuracy springs are available upon request.
Standard operating temperature from 17°C, maximum working temperature is dependent on O-Ring material. Low temperature option (-252°C) is available.
