Air Compressor Pilot Unloader Valve Adjustment

This causes the unloader valve to open and vent the excess air from the compressor to the atmosphere.

Air compressor pilot unloader valve adjustment.

Piloted unloader valves combine a pilot valve and an unloader valve to run an air compressor continuously. This causes the unloader valve to open and vent the excess air from the compressor to the atmosphere. This component is responsible for. Pilot valves are used on gas engine or electric motor driven compressors where the compressor is to maintain a constant pressure range while running continuously.

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. The pilot remains closed until the downstream pressure reaches the unload setting.

Check operation of pilot valve and adjust if required as detailed in adjusting pilot valve instructions below. As the compressed air is used and the pressure drops to the load setting the pilot closes and depressurizes the unloader valve. The pilot then opens and pressurizes the unloader valve. 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.

Top end setting fine tuning instructions make sure the toggle lever is positioned. How to adjust unloader valve on your air compressor how to adjust unloader valve on air compressor. Your electric cutouts are shutting off the motor but not unloading the compressed air over the piston. Failure to do so could result in serious injury.

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. While this type of valve is most commonly used on gas powered air compressors it can also be used on electric models. The pilot then opens and pressurizes the unloader valve. Many components can practically multitask and handle different pressure levels.

Piloted unloader valve adjustment do not set up operate or service this componentuntil you read and fully understand the air compressor owner s manual. Adjusting pilot valve instructions operation.
