Domestic Hot Water Mixing Valve

Product description

A self-actuating thermostatic domestic hot water mixing valve acts as a central mixing unit and ensures a constant mixed water temperature at the point of withdrawal. Scalding at the point of withdrawal is thereby avoided even at high tank temperatures. Special valve seals at the control piston reduce unwanted admixtures to a minimum*, resulting in maximum utilisation of the tank temperature. Long service life thanks to high-quality plastics and non-stick coatings against limescale. Infinitely adjustable target temperature.

Mode of function
The mixing valve is supplied with hot water from a tank and with cold water from the line network. The temperature of the mixed water is registered by a thermostatic expansion element. A deviation in the temperature of the mixed water from the target value will cause the expansion element to move the control piston, and thereby regulate the supply of hot and cold water until the mixed water temperature corresponds to the target value.
