Ingersoll Rand OEM 23134968 Minimum Pressure Check Valve Rebuild Kit

The 23134968 minimum pressure check valve (MPCV) kit will fit almost all of the small Ingersoll Rand UP6 series compressors below (with and without integrated dryers). This kit contains all parts necessary to succefully rebuil the MPCV.

  • UP6-5
  • UP6-7.5
  • UP6-10
  • UP6-15C

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. The MPV will thread onto the backside of the cooler on IR’s UP6 models.

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