Mixing valves 3F, 4F


Mixing valves 3F, 4F are used in central heating. Three-way mixing valve is used primarily to reduce the temperature of heating circuit such as floor heating systems. Four-way mixing valve in addition to temperature control circuit protects the boiler / heat source from a low return temperature. Fully automatic operation of the valve can be provided by the motor from WOMIX like MP 10 or MP 15.
