The HU Unloader Pilot Valve with a Hand Unloader is Used on Gasoline Driven Compressed Air Systems for Constant Run Applications to Actuate Another Device Using a Pneumatic (Air) Signal. Unloader Pilot Valves Always Work in Conjunction with Another Device i.e. Actuating a Throttle Control to Slow Down and Speed Up an Engine, Opening and Closing a Discharge Valve to Vent Air to Atmosphere, or Operating the Intake Unloaders in the Compressor Head.

Unloader Pilot Valves Operate in a Set Pressure Range. The Maximum Setting is the Unload Pressure and the Minimum Setting is the Load Pressure. During Unload, the Pilot Valve Will Actuate and Open Another Device While at the Load Pressure the Pilot Valve Closes and Returns the Compressor to Normal Operation.
