Air Compressor Pilot Unloader Valve Adjustment

When the the air compressor unloader valve is working correctly the pressure in the tank has dropped to below the normal cut in pressure level of the pressure switch the pressure.

Air compressor pilot unloader valve adjustment.

This causes the unloader valve to open and vent the excess air from the compressor to the atmosphere. Failure to do so could result in serious injury. Piloted unloader valves combine a pilot valve and an unloader valve to run an air compressor continuously. The pilot remains closed until the downstream pressure reaches the unload setting.

As the compressed air is used and the pressure drops to the load setting the pilot closes and depressurizes the unloader valve. The compressors have an unloader valve to bleed off the compressed air over the piston when the compressor stops so that there s less load when it goes to start. The pilot then opens and pressurizes the unloader valve. How to adjust unloader valve on your air compressor how to adjust unloader valve on air compressor.

Check operation of pilot valve and adjust if required as detailed in adjusting pilot valve instructions below. The pilot then opens and pressurizes the unloader valve. While this type of valve is most commonly used on gas powered air compressors it can also be used on electric models. Your electric cutouts are shutting off the motor but not unloading the compressed air over the piston.

This causes the unloader valve to open and vent the excess air from the compressor to the atmosphere. An air compressor has a lot of different components that are quite versatile. This component is responsible for. The piloted unloader valve is one of those components.

Piloted unloader valve adjustment do not set up operate or service this componentuntil you read and fully understand the air compressor owner s manual. As the compressed air downstream is used and the pressure drops to the load setting the pilot closes and. A failed air compressor unloader valve is one of the most common reasons why your air compressor cannot restart after you have used air from the compressor tank.
