Champion Z5117 Z11937 High Pressure Intake Valve Assembly

The Champion Z5117 Z11937 High Pressure Intake Valve Assembly is an OEM replacement part for Champion air compressors, identifying the same valve assembly across two part numbers to match different catalog references used by distributors. This steel valve assembly includes gaskets and is designed to seal the intake port under high pressure, helping restore proper piston charging and maintaining compressor performance in demanding operation. Recognized in Champion part catalogs and by distributors as Z11937, it is documented as the high‑pressure intake valve assembly for Champion units, with multiple sources listing it as the replacement HP inlet valve for Champion compressors. Typical applications involve replacing a worn or leaking HP intake valve in Champion air compressors to maintain efficient intake and compression, and to extend service life of the pump assembly. When selecting this part, verify compatibility with your Champion model by confirming the OEM reference Z11937 (and the Z5117 cross‑reference), ensuring the correct mounting interface and gasket set are included for reliable installation and seal integrity.
