Abstract

The present seal ( 10) is a disc of a rigid but deformable plastic, the top surface of which is cylindrical, and the bottom of which has a circular groove (12) containing a flexible sealing mechanism (15). This seal is suited for use in a ganged rotor valve (22) having two or more levels of independent fluid passageways through the rotor along the length thereof. Each level will usually have two independent L-shaped passageways (34, 35). The seal (10) of this invention fits into the rotor about each of the ends of the passageways (34, 35) to seal the passageway between the rotor and the valve body (22).
