A selectable temperature mixing valve delivering, from hot and cold water supplies, water at hot, cold and one or more intermediate temperatures in volume set by the degree of actuation of respective pushbutton actuated operators controlling displacement of valving members relative to inlet ports in corresponding valving sections, single ported for hot and cold delivery and double ported for mixed water in each section for intermediate temperature delivery; and in which initial intermediate temperature mixed flow is restricted at a point in the mixed flow path to ensure temperature stability with changing flow rate.
