Champion VP1055830 Pressure Switch With Unloader

Champion VP1055830 Pressure Switch With Unloader is a four-port, 1/4" FNPT control valve designed as a replacement part for Champion air compressors. It provides a 26-amp electrical rating and a switching range of 140–175 psi, enabling automatic on/off control as the system pressure changes. The unit includes an integrated unloader valve that vents the compressor head pressure when the switch opens, easing motor start-up and reducing load on restart. Four 1/4" FNPT ports support flexible inlet, outlet, and accessory connections, making it suitable for configurations that require multiple connections and the ability to integrate an unloader line. This VP1055830 model is widely cataloged across supplier networks as the Champion pressure switch with unloader, offering a reliable, straightforward replacement for compatible Champion-based systems.
