ABSTRACT:
A water conditioner rotary valve (18) is substantially formed of plastic and designed to provide fluid type valving without requiring gaskets or precision forming of valve elements while operating in a highly efficient manner by reducing shear stress and rotative friction. The valve seat (100) has a series of raised ribs (105, 105') on both sides (103, 104) to provide a sealing engagement against a substantially planar surface (84) of a housing plate member (80) and against a substantially planar surface (119) of a rotor assembly (115). The rotor assembly (115) features a valving plate member (116) interconnected to a ported cover (117) through interlocking butterfly shaped ridges and grooves (129, 140, 132, 143) to substantially reduce rotative shear stress while further providing fluid channels (150, 151) to provide selected fluid flow paths through the rotary valve (18) in response to the selective alignment of the rotor assembly (115).
