Ingersoll Rand 39475637 OEM Minimum Pressure Check Valve Assembly

The 39475637 MPCV will fit several of the Ingersoll Rand EP series rotary screw compressors manufactured in the 1990's to early 2000's. The minimum pressure check valve keeps air pressure inside of the sump during the initial startup of the compressor. This helps the oil circulate throughout the compressor on start-up. Once the pressure inside of the oil sump reaches approximately 60psi, the valve will open and let compressed air flow downstream.

A properly functioning MPCV will prevent oil carryover into your piping system. This will also prevent high pressure air from your receiver and air piping from re-entering internal compressor components. If air is leaking from the inlet after the compressor has been shut off for a period of time, there is a good chance that this valve failed and is letting high pressure air flow back inside of the compressor. 

This is an OEM minimum pressure check valve made from Ingersoll Rand
