Abstract: The valve is of the type that includes a single operating handle for controlling both the proportioning between hot and cold water flow and also the volume of flow. The valve comprises a body having hot and cold inlet passages and an outlet duct, a ball-shaped control member, a rigid stationary liner receiving the control member and having position limiting tabs associated therewith, and a resilient diaphragm disposed intermediate the liner and valve seat of the body. The liner has a pair of apertures for accommodating a corresponding pair of nipples on the diaphragm which are displaceable toward and away from the inlet passages for controlling the flow of fluid therefrom. The opening of the inlet passages into the seat is constructed to provide a uniform load about the passages for the diagram in the seat.
