ABSTRACT:
A fluid valve suitable for use in slush pumps is disclosed. The valve includes an elastomeric seal and a metal wear ring held in place on a valve body by a retaining ring. Thrust of the valve body against a valve seat is absorbed by the wear ring which is held against a shoulder on the valve body. The elastomeric seal is held between the valve body and the wear ring. A second seal is disposed between the inside diameter of the wear ring and the valve body to prevent fluid leakage behind the wear ring. The structure of the valve provides for replacement of the wear ring.
