This single component can activate an engine idle control divert air from the tank when it reaches the top pressure setting and can reduce oil consumption by equalizing pressure between the pump and check valve.

Compressor unloader valves are common pieces of equipment on many types of air compressors including reciprocating rotary screw and even gasoline or other fossil fueled air compressors. This big valve is further controlled by a small pilot valve. There are few components on an air compressor that can multi task quite like the piloted unloader valve.
