Campbell Hausfeld VT470800AJ Valve Plate Assembly

Campbell Hausfeld SPEEDAIRE VT470800AJ Valve Plate Assembly is a replacement valve plate kit designed for VT470-series air compressor pumps used in Campbell Hausfeld and Speedaire equipment. It is intended to renew the valve plate in VT470000KB and VT470200KB pump heads, restoring the efficiency of the intake/exhaust paths and the head seal. The kit is associated with part numbers TQ011300AJ (valve plate assembly) and TQ011200AV (molded seal); production changes documented by Campbell Hausfeld indicate that kits produced on or after October 17, 1996 contain the TQ011300AJ plate and the TQ011200AV seal as a pair, replacing older gasket configurations such as XA011301AV. In many parts catalogs this VT470800AJ designation appears as the valve plate kit for the VT470 family, with some listings describing a quad valve plate assembly that includes the valve plate (with valves installed) and the accompanying upper and lower gaskets. This replacement part is compatible with VT470-series pump heads, so before purchasing you should verify your exact VT470 model (for example VT470000KB or VT470200KB) to ensure proper pairing with the VT470800AJ kit contents. Using this assembly helps restore compressor performance by renewing the critical valve-and-seal interface in the head, enabling reliable cycling and sealing without replacing the entire pump head.
