A water temperature sensing/flow control mixing valve has a valve body with hot and cold water inlets and at least one outlet. A mixing valve member is positioned within the valve body and controls the proportion of hot and cold water that flows from the outlet. A water flow restrictor is positioned within the valve body and movable from a normal flow position in which outlet flow is unobstructed to a position in which the restrictor partially closes the outlet to limit flow therefrom. There is a shaped memory metal actuator positioned within the valve body to move the restrictor from the normal flow position to the flow limiting position when the water within the valve body exceeds a predetermined temperature.
