NPT Check Valves

These check vales are threaded, one-way valve that may be used to route liquid or gas through a threaded manifold, piping system, or equipment panel. The most common applications used would be for a compressed gas system using Carbon Dioxide (CO₂) or hydraulic systems where backflow could damage, contaminate and make a system inefficient. We have commonly seen that this style of check valve is used in tandem with our other product lines, such as the cryogenic regulators.
