Primary pressure control circuit description

Primary pressure control circuit

It is used to control the air tank of the air compressor station so that its pressure does not exceed the specified pressure; As shown in the figure. Usually use external control relief valve to control, also can use the pressure gauge with live contact to replace the relief valve to control the start and stop of air compressor motor. The circuit is simple in structure and reliable in operation.

Among them: 1 - relief valve, 2 - pressure gauge
