Description
The thermostatic mixing valve R156-2 is installed on household sanitary systems in order to achieve energy savings, greater comfort in the use of hot water, elimination of risks of skin burns caused by excessive operating temperatures. For this reason the valve is equipped with a thermal shutdown function in case of failure of the cold water supply. It can be used in boiler room at sanitary hot water risers in the immediate vicinity of wall boilers or water tanks, or in distribution cabinets in case of sanitary systems supplied by manifolds.
It is fundamentally important to install the valve on downstream of boilers in solar system installations where the water temperature in storage tanks, especially in summer, reaches very high levels, well above the temperatures of ordinary use.
A wax bulb inside the valve is immersed in the mixed water 'ow assisted by a balanced system of springs. The valve operates by fast shifts of a few tenths of millimetre carried out depending on the changing temperatures of the hot and cold water supplies to ensure that the required temperature of mixed water is maintained.
