Operation
A thermostatic mixing valve mixes hot and cold water in such a way as to maintain the set
temperature of the mixed water at the outlet.
A thermostatic element is fully immersed into the mixed water. It then contracts or expands
causing movement of the piston, closing either the hot or cold inlets, regulating the flow rates
entering the valve.
If there are variations of temperature or pressure at the inlets, the internal element automatically
reacts attempting to restore the original temperature setting.
Thermal shut off
In the event of a failure of a the hot or cold supply, the piston will shut off, stopping water
discharging from the mixed water outlet.
The Caleffi valve requires a minimum temperature differential from hot inlet to mixed water outlet
of 10°C to ensure the correct operation of the thermal shut off feature.
