303-3381 - PILOT/UNLOADER VALVE 140-175 PSI

The pilot/unloader valve controls the airflow from your pump to your tank, and also controls your engine speed, together with the throttle/idle control valve. It acts as the “brain” of your compressor. The valve pressure settings (cut-in and cut-out pressures) is almost always pre-set at the factory, but these settings are also adjustable. Replace if it leaks, chatters, or no longer cuts the unit in or out at the required pressure. There are many types and configurations of pilot valves: some have built-in check valves and unloader ports, depending on the configuration of the unit.
