Piston-Type Check Valves

Our piston check valves offer bubble-tight sealing capabilities at low pressure drops. They can be used as tank check valves for small compressors, or as components in pneumatic circuits.

Valve bodies and pistons are brass with fluorocarbon o-rings and stainless steel springs. 250 PSI max pressure, 250°F max temperature. Available in a variety of inlet/outlet configurations and orifice sizes. See table for available configurations.

Bar Stock Poppet-Type Check Valves

Our "IC" in-line check valves were created around our "B2" design. For those compressor applications where an in-tank valve will not fit, an "IC" valve can conveniently be installed right in the discharge line of the compressor.

Brass bodies, glass-filled fluoropolymer poppets, and stainless steel springs insure long life. Comes standard with 1/8" NPT unloader port. 450 PSI maximum pressure, 400°F maximum temperature.

Cast Brass Check Valves

These cast-brass check valves have been specifically designed for installation into air compressor discharge lines. Extra-heavy walled cast brass bodies, glass-filled fluoropolymer poppets, and stainless springs resist corrosion and insure long life.

A plugged, 1/8" NTP unloader port is standard. 250 PSI maximum pressure, 450°F maximum temperature.
