Pilot Valves

Conrader 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 a 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.

The cyclic process can be used to operate the following:

  • Throttle controls to regulate engine speed.
  • Unloader valves to control a compressor.
  • Drain valves to removed condensate from systems.
  •  Normally open/close valves.
  • Shuttle valves

The manual hand unloader lever can be replaced with the dual control lockout for use on electric motor compressors to switch between start/stop and continuous operations.
