Champion R30 R30A R30C R30D Valve Rebuild Kit

Champion R30 R30A R30C R30D Valve Rebuild Kit is a maintenance part designed to refresh the valve assembly on Champion R30‑series air compressors, covering models R30, R30A, R30C, and R30D. It targets a single compressor head, supplying replacement components so the head can be reconditioned and return to proper operation. In Champion's valve‑head overhaul catalogs, the Z5157 complete valve kit for the R30D head includes valve discs, unloader springs, plus valve and unloader gaskets and air filter elements, enabling a full refresh of the head. Other rebuild‑style listings describe kits that bundle a gasket set, piston rings, and oil seals with wear parts such as valve discs and springs to restore head reliability. These parts are intended for routine maintenance or repair to reduce leakage, restore unloading function, and extend the service life of the R30‑series head. Use this kit when servicing Champion R30, R30A, R30C, or R30D compressors to refresh the valve area and support reliable air delivery.
