ABSTRACT:
A mixing valve arrangement for producing temperature controlled water wherein an electromagnetically actuatable supply valve is coupled in each of the hot and cold water supply lines is described. Electronic control loop circuits generate a temperature control signal from both a temperature preselector and a temperature detector and a volume control signal from both a volume preselector and a mixed water flow volume detector. An electronic decoupling circuit is interposed between the two control loop circuits and the valve actuating circuits to derive control signals representative of the degree of opening of the two supply valves from the temperature and volume control signals.
