The 1312100167 check valve is an OEM one way valve from Chicago Pneumatic. This is used on several of the premium packaged industrial reciprocating compressors. Typically this is connected directly to the air cooled aftercooler and has a stainless steel braded line connected to the valve and pump. The check valve is a one way valve designed to keep air from escaping from the pump into the tank. You will know the check valve is bad if air is leaking continuously from the pressure switch after shutdown.
