Minimum pressure valve
The minimum pressure valve can make the compressor quickly establish enough
high and low pressure difference in a short time once the compressor starts. When the
compressor starts running, the minimum pressure valve ensures the internal oil supply
pressure of the compressor. Thus, the compressor capacity adjustment and loading is
smooth, so it's especially suitable for the air-cooled heat pump and the compressor
which has insufficient supply pressure differential caused by the seasonal reasons. The
minimum pressure valve also has a check valve's function ,When the compressor
stops, the minimum pressure valve will quickly cut off the compressor's connection to
the exhaust pipe to prevent the high pressure gas flow back into the compressor, so as
to avoid the long-term reversal of the compressor effectively.

pressure valve.
