CV25 SERIES CHECK VALVES
CV25 SERIES CHECK VALVES
CV25 Series check valves is an adjustable one-way valve designed to enable unidirectional fluid flow while preventing media backflow. It's commonly used in high-pressure industrial applications — including laboratories, instrumentation systems, chemical production, and high-pressure test equipment — where precise flow direction control is required in medium-to-high pressure gas systems.
Features
Maximum operating pressure: 3000 psi (207 bar)
Nominal opening pressure adjustable from 3 to 600 psi
Inlet & Outlet Connection: FSR, NPT and GENLOK
Optional 316 stainless steel or brass material
Check valves are tested for opening and re-sealing performance with leak detection fluid during production
Cleanliness: Complies with the product cleanliness requirements specified in ASTM G93 Class C
