A mixing valve adapted for proportioning hot and cold water and for initiating and terminating flow. The valve body has fluid passages terminating in spaced apart hot and cold water inlet ports and an outlet port to a circular valve seat. A generally cylindrical closure member is rotatable about its axis within the valve body with one end overlying the valve seat so as to cover and seal the inlet ports in a closed position. The closure member has a particularly configured recess such that upon rotation of the closure member from the closed position the recess progressively overlies and seals the inlet ports to initiate and provide a mixing of flow. A sequence of flow from cold to warm to hot is assured by a stop which is adjustable to preset a maximum temperature of outlet flow. The closure member can be easily modified for installations where the hot and cold water inlet pipes are reversed from their conventional relative positions.
