Champion M2854 Air Compressor Pilot Unloader Valve

Champion M2854 Pilot Unloader Valve is an OEM replacement part for Champion air compressors, and it actuates the head unloader mechanism to enable starting and stopping the compression cycle without shutting off the engine. It is rated for a 90-120 psi unloading range, with some Champion manuals noting a 125 psi discharge, and vents air to the head at set pressure to reduce the load during motor startup. The valve is used with Champion R-Series units and related unloader assemblies, providing the pilot control that governs when the compressor unloads during the pressure cycle. This part installs in the pilot-valve position on compatible Champion systems, restoring proper unloading and restart behavior in the compression cycle.
