Air compressor two effects of minimum pressure valve:

1, the minimum pressure valve is used to buffer, when the machine load moment, we assume that the emissions into the atmosphere, the machine internal separation before and after the separation of large pressure difference will all add on separator, cause the harm of separator core;

2, watch oil lubrication is to rely on the pressure difference between the machine itself, no additional auxiliary pump, when the machine in the idle state, still need to maintain certain pressure oil circulation, so the inlet valve is relatively closed, and the minimum pressure valve to prevent leakage, such guarantee oil circulation.
