Air Compressor Pilot Unloader Valve Adjustment

Failure to do so could result in serious injury.

Air compressor pilot unloader valve adjustment.

The pilot remains closed until the downstream pressure reaches the unload setting. 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. How to adjust unloader valve on your air compressor how to adjust unloader valve on air compressor. This component is responsible for.

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.

While this type of valve is most commonly used on gas powered air compressors it can also be used on electric models.

Piloted unloader valves combine a pilot valve and an unloader valve to run an air compressor continuously. The pilot then opens and pressurizes the unloader valve. This causes the unloader valve to open and vent the excess air from the compressor to the atmosphere. 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.

Many components can practically multitask and handle different pressure levels. 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. The piloted unloader valve is one of those components. Check operation of pilot valve and adjust if required as detailed in adjusting pilot valve instructions below.

As the compressed air downstream is used and the pressure drops to the load setting the pilot closes and. Your electric cutouts are shutting off the motor but not unloading the compressed air over the piston. 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.

Piloted unloader valve adjustment do not set up operate or service this componentuntil you read and fully understand the air compressor owner s manual. This causes the unloader valve to open and vent the excess air from the compressor to the atmosphere.
