Air compressor pilot unloader valve.

What the unloader valve does is that is responds to the compressor pressure switch turning the power off to the motor and allows any air that may be trapped over the piston or pistons on a multi cylinder air compressor to vent to atmosphere removing any load that the trapped air may have created over the cylinder piston. Unloader valves are used to release pressure from air receivers where there is no mechanism to automatically stop the compressor for example on petrol or diesel air compressors. 4 port air compressor pressure switch control valve 95 125 psi electric unloader.

As the compressed air downstream is used and the pressure drops to the load setting the pilot closes and depressurizes the unloader valve. While the air compressor is running the pilot remains closed until the pressure reaches the unload setting. Top end setting fine tuning instructions make sure the toggle lever is positioned. While this type of valve is most commonly used on gas powered air compressors it can also be used on electric models.

This causes the unloader valve to open and vent the excess air from the compressor to the atmosphere. Piloted unloader valves combine a pilot valve and an unloader valve to run an air compressor continuously. The unloader idle piston is a device that once the unloader valve is activated brings the revs of the engine down to idle so both compressor and.
