A fluid mixing valve is disclosed having three pressure operated pilot controlled solenoid operated valves (12, 14, 16) mounted on a unitary valve housing (10) which defines a primary fluid passageway (74) an outlet (76), and two inlet fluid passageways (81, 85) connectable to separate pressurized fluid sources. The solenoid valves selectively control fluid flow from the inlet passageways to the primary passageway which also functions as a mixing chamber. Flow control orifices (78, 80, 82) integrally molded into the valve housing are disposed intermediate the primary fluid passageway and the respective inlet passageways for limiting the flow rate to the outlet.
