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 decreases and the load (cut-in) pressure is achieved, the pilot valve closes and depressurizes the line downstream of the pilot valve. This RCT1-F1-145-175 pilot valve features 1/4" female NPT inlet and 1/8" female NPT outlet threads and has a pre-set pressure range of 145-175 PSI. This works as a great replacement for the M2853 that is commonly found on Champion Air Compressors. This pilot valve does not have a manual lever for the unloader.
