Abdex’s range of High Pressure Check Valves is engineered to provide reliable, unidirectional flow control for demanding fluid and gas applications. Designed for secure shut-off when pressure drops below the cracking threshold, these valves are not intended for use as relief valves.
Manufactured from durable 316 stainless steel, our check valves feature a resilient O-ring seat for noise-free operation and leak-free sealing. They are available in a wide variety of series—including 10C, 15C, 20C, and 60C—each offering specific pressure ratings from 10,000 psi up to 60,000 psi to suit your system requirements.
Choose from O-ring and ball check valve designs with various end connections such as NPT and tube fittings, and orifice sizes ranging from 0.094″ to 0.688″. Optional O-ring materials including FKM, FFKM, EPDM, NBR, and Kalrez support extended temperature ranges from -110˚F to 1200˚F (-79˚C to 649˚C), ensuring performance in extreme environments.
Whether you need reliable sealing in instrumentation, hydraulic, or gas systems, Abdex High Pressure Check Valves deliver consistent, high-performance operation under extreme conditions.
