ABSTRACT:
A specific physical characteristic (temperature) of a mixture of two liquids in a mixing chamber (14) is controlled by progressively opening a valve member (35) of a selected valve (10,11) through which one of the liquids flows while the other liquid flows through the other valve, and if the temperature of the mixed liquids has not reached a desired level, the selected valve is left fully open while the other valve is progressively closed to adjust the temperature to that desired. The opening and closing of the valves is controlled in response to signals from a sensor in the mixing chamber.
