Function
The thermostatic mixing valve is used in solar thermal systems for
the production of domestic hot water.
It is designed to maintain the set temperature of the mixed water
supplied to the user when there are variations in the temperature
and pressure conditions of the incoming hot and cold water or in
the flow rate.
It is also fitted with an anti-scald safety function, which immediately
shuts off the hot water flow in case of a failure in the cold water
supply at the inlet.
This particular series of mixing valves can function continuously at
the high temperatures of the incoming hot water from the solar
storage tank.
