Ingersoll Rand OEM 22064695 Minimum Pressure Check Valve Service Kit for UP6 20-30hp Compressors

Ingersoll Rand OEM 22064695 Minimum Pressure Check Valve Service Kit for UP6 20-30hp Compressors

This is the minimum pressure check valve kit used to replace the internal parts of the complete minimum pressure valve. The Kit consists of the necessary springs, conical o-ring, Piston Guide, retainer cap, and piston assembly.

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 kit will replace the parts on the Ingersoll Rand 22099352 & 54731583 check valves.
