Industrial Z812 Low Pressure Intake Valve Assembly

Z812 is Champion's OEM low-pressure intake valve assembly for Champion air compressors, supplied with gaskets for a complete replacement on the low-pressure side of the intake system, and designed to restore the seal between the valve plate and cylinder after wear or leakage. The assembly (OEM reference Z812) is used on Champion R-series models, including R15, R30, and R15B two-stage configurations, to replace a worn or leaking intake valve and to maintain proper air admission during the suction stroke, which helps stabilize cut-in pressure and overall pump efficiency. Included are the valve and gaskets, and the kit is intended to be installed with standard valve-seat surfaces after cleaning, ensuring correct alignment with the corresponding seat and preventing air leaks that could reduce performance or cause premature wear of the compressor's intake path. This part is commonly listed in Champion catalogs and supplier listings under OEM reference Z812, and buyers typically seek it as a direct, factory-verified replacement for R15/R30 family machines when servicing low-pressure intake components.
