All of our Minimum Pressure Valves are 100% OEM compatible and are formulated to achieve the best possible results in each application.


Minimum pressure check valves or MPCV’s as known in the compressor world, serve two functions.

First, the MPCV remains closed upon start up of the compressor allowing the unit to build to a preset pressure. The valve then allows the compressor to maintain a steady stream of lubrication throughout the compressor as the unit loads and unloads through the performance cycle of the compressor.

The MPCV also closes the system pressure off from the compressor so that no system air can return to the compressor package causing a “back charge” effect and possibly collapsing the separator.
