Unloader Control Pilot Valve with Mounting Boss for Air Compressors -

Pilot Valves are used on compressed air systems to control other devices using a pneumatic signal. The pilot valve is factory set in a pressure range with an unload (cut-out) and load (cut-in) setting. As the system pressure increases and the unload (cut-out) pressure is achieved, the pilot valve opens and pressurizes the line downstream of the pilot. As the system pressure deceases and the load (cut-in) pressure is achieved, the pilot valve closes and depressurizes the line downstream of the pilot valve.
