Service Minimum pressure check valve (MPCV) service kit

The minimum pressure check valve (MPCV) shall be frequently tested and regularly maintained. Remove it from the compressor for testing. If operating conditions are particularly severe, the frequency of testing and maintenance shall be increased accordingly.

The user shall establish the frequency of such tests as it is influenced by such factors as the severity of the operating environment. For R30-37, the MPCV is installed as part of combination block.

The minimum pressure check valve (MPCV) should be tested and recalibrated in accordance with any national or local codes that may exist. If no code exists, Ingersoll Rand recommends that the valve is recalibrated at intervals of one year by a licensed contractor or qualified service personnel.
