Abstract An automatically operating valve for regulating water flow, especitially a mixing valve for automatically mixing hot water and cold water to obtain a mixedwater of a desired temperature is disclosed. This automatically operating valve for regulating water flow or the mixing valve is characterized by employing piezoelectric actuators for operating valve body means thereof. Due to such a construction, the valve can not only fully close or open but also carries out the fine flow amount control by regulating the opening rate or angle of the valve body means. Especially in case the automatically operating valve is the mixing valve, the mixing ratio of hot water and cold water can be accurately regulated so that the mixed water of a desired temperature can be always automatically obtained.
