Champion Z273 Low Pressure Intake Valve Assembly

The Champion Z273 Low Pressure Intake Valve Assembly is a replacement part for Gardner Denver Champion R40A and R70A piston-type pumps, designed to control the intake phase in the low‑pressure portion of the compression cycle and seal against the cylinder with an accompanying gasket. In Champion and Speedaire catalogs, Z273 is listed as the low‑pressure intake kit for R70A family units and is cross‑referenced to Speedaire Z273, reinforcing compatibility with common 1WD30/1WD36/1WD37/1WD38/1WD40/1WD44 drive configurations. The associated gasket, P07352A, is the standard sealing component used with this valve assembly, ensuring proper seating and leakage resistance. This valve assembly is used during maintenance and repair to restore proper intake flow and minimize leakage, helping to preserve the efficiency and performance of R40A/R70A compressors. Retail listings frequently describe Z273 as including gaskets, aligning with typical OEM practice for valve kits and supporting a straightforward replacement without additional parts hunting. With its targeted design for the R40A and R70A series, the Z273 offers a direct, drop‑in replacement that reduces downtime and maintains the expected throughput of Champion air‑compression systems.
