Check Valve Stainless Steel 1 PSIG Cracking Pressure 1/4" NPT Female X 1/4" NPT Female Model 8420V

Check valves prevent the return flow of gas, thus keeping foreign substances out of lines, regulators, and cylinders located upstream of the valve.

These valves are a spring loaded design with the spring on the high pressure side to protect it from foreign substances. The positive stop prevents over-stressing of the spring by sudden surges of gas pressure. An o-ring at the valve seat provides quick, efficient sealing. Stainless steel Max pressure 3000 PSIG.
