Operating principle 5212 SinkMixer
TM
The thermostatic mixing valve mixes hot and cold water in such a way as
to maintain constant set temperature of the mixed water at the outlet. A
thermostatic element is fully immersed into the mixed water. This element
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 to restore the original temperature setting. In the event
of a failure of either the hot or cold supply, the piston will shut off, stopping
water discharging from the mixed water outlet.

Thermal shutoff
In the event of a failure of the hot supply port, the piston closes the cold
supply port. Similarly, if the cold water supply fails, the piston closes the
hot supply port. The Caleffi 521201A thermostatic mixing valve requires a
minimum temperature differential from hot inlet to mixed water outlet of 18°F
(10°C) to ensure the correct operation of the thermal shutoff feature.
