Champion HGR7-3H Valve Set With Head Unloaders And Gaskets

Champion HGR7-3H valve set with head unloaders and gaskets is a direct-replacement kit for Champion air compressors that use head-unloader configurations, including the HGR7-3H and HGR7-3K models. The kit includes a complete valve set and a gasket set, designed to replace worn valve components and seals and to accompany head-unloader assemblies. In Champion cylinder groups configured with head unloaders, the unloaders vent cylinder pressure during startup to reduce starting torque and help the pump re-seal once running. This replacement parts kit aligns with Champion's repair parts structure for HU configurations, with valve sets and gasket sets listed as standard repair components for head-unloader systems. Typical applications include servicing R-series Champion compressors or other HU-equipped units where valve and gasket wear has impacted performance.
