Air Compressor Pilot Unloader Valve Adjustment

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.

Air compressor pilot unloader valve adjustment.

The pilot then opens and pressurizes the unloader valve. 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. 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. 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. Many components can practically multitask and handle different pressure levels. Top end setting fine tuning instructions make sure the toggle lever is positioned. 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. Adjusting pilot valve instructions operation. The piloted unloader valve is one of those components. 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.

Piloted unloader valve adjustment do not set up operate or service this componentuntil you read and fully understand the air compressor owner s manual. The pilot remains closed until the downstream pressure reaches the unload setting. While this type of valve is most commonly used on gas powered air compressors it can also be used on electric models. An air compressor has a lot of different components that are quite versatile.

This component is responsible for. As the compressed air downstream is used and the pressure drops to the load setting the pilot closes and. This causes the unloader valve to open and vent the excess air from the compressor to the atmosphere. How to adjust unloader valve on your air compressor how to adjust unloader valve on air compressor.

The pilot then opens and pressurizes the unloader valve. While the air compressor is running the pilot remains closed until the pressure reaches the unload setting.
