Low Pressure Stainless Steel Check Valve

304 Stainless steel check valve with low cracking pressure for excellent corrosion resistance.

The valve seat connection is metal to metal. The Check valve is serviceable by unthreading one of the sides. The threaded connection is sealed by a PTFE washer.

Note: Check valves are used to direct flow in one direction. Check valves do not create a 100% seal. It is common for a few drips per minute to flow in the backwards direction when the fluid is stagnant. Ball valves should be used for a complete stop against backflow in a stagnant application.
