Ingersoll Rand OEM Minimum Pressure Check Valve for RSA11-22I, RSA15-22N

Ingersoll Rand 100015593 OEM Minimum Pressure Check Valve for RSA11-22I, RSA15-22N

100015593 is a minimum pressure check valve kit used on the Ingersoll Rand RSA11-22I and RSa15-22n rotary screw air compressors. 100015593 is the complete minimum pressure valve. 

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 100015593 MPCV service kit is used on the following Ingersoll Rand compressors

• RSa11i
• RSa15i
• RSa18i
• RSa22i
• RSa15n
