Abstract
A single-control valve has a normally stationary valve plate formed with hot- and cold-water inlet ports and an outlet port opening at a flat face of the valve plate and a movable control plate having a flat face lying on the valve-plate face and formed with a cavity opening at the control-plate face and juxtaposable over the ports. at least one of the plates and its surface are formed of a hard ceramic, and at least the surface of the other of the plates is formed of a low-friction synthetic resin. The low-friction synthetic resin is polyethylene or polypropylene.
