Check Valves

Ideal for cryogenic pressure vessel (vapor area), manifolds and other demanding applicationsNot recommended for corrosive gases or liquid cryogenic applications

Machined high quality brass with stainless steel operating spring and valve discPrevents reverse flow at point of originEasy to install

Reverse flow check valves help to prevent the reverse flow of gases from traveling past the check valveDisk assembly seals tight against seat in event of reverse flow

Heavy duty check valves are designed for high performance in demanding applicationsAll styles feature low/open/close pressuresCheck valve seat material is durable Ethylene Propylene (EPDM)For use in high pressure pigtail assemblies

Check Valves are appropriate for applications that require higher operating pressures, up to 200 PSIGCompact design and low/open/close pressures: 3 oz. to open valve and 10 oz. or reverse pressure for positive valve closing

Easily mounts on outlet bushing on a regulator having a B-Size outletThis model has the same flow capacity as the torch - type (1200 SCFH at 50 PSIG) when installed on a regulatorCheck valve is easily seen and is less subject to contamination, abuse and...

Reverse flow check valves help to prevent the reverse flow of gases from traveling past the check valveDisk assembly seals tight against seat in event of reverse flow

For torch and regulator applicationsGuards against danger caused by plugged tips, over-pressurizing or incorrect startup proceduresHelps prevent accidents caused by gases mixing in hoses, regulators or cylinders
