1089058022 Atlas Copco: When the system pressure is lower than the set lower limit value, the electromagnetic valve unload device receives the control signal. The electromagnetic coil is energized, and the valve core moves to open the intake channel. The air compressor enters the loading state and starts to compress air and supply it to the system.

When the system pressure reaches the set upper limit value, the electromagnetic valve is de-energized, the valve core returns to its original position, closing the intake channel. At the same time, it may open the unload channel to release the residual pressure in the cylinder. The air compressor enters the unloading state, stops generating air but remains idling to avoid frequent start-stop.
