BLANKING PLUG; FOR UNLOADER VALVE 312013…/ 312017…/ 3120

The governor valve, which is usually compressor mounted, operates in conjunction with the compressor and maintains reservoir air pressure between a predetermined maximum and minimum pressure.

The unloader valve allows the air compressor to operate in an unloaded state, where the compressor piston continues to reciprocate, but does not build additional air pressure in the vehicles compressed air system.
