A valve body presents a planar discharge surface having spaced hot and cold inlet orifices with an outlet orifice generally centered on an axis between them. A cap of inverted cup shape has a rim sealed with respect to the discharge surface and has a circular end wall with an axial opening formed therein. Arranged on the axis is a rotor having a shaft which extends through the axial opening and which is in the form of a disc having a plurality of hollow pedestals with blind openings facing the discharge surface. Resilient sealing pads are respectively telescoped into the blind openings, each sealing pad having an associated coil spring for biasing the pad into engagement with the discharge surface.
