Fan Coil Unit Control Valve
Model: 5219, External Thread
The tempering valve is used in systems for the domestic hot water production. Its function is to maintain the temperature of the mixed water supplied to the user constant at the set value when there are variations in the conditions of the hot and cold water at the inlet. The tempering valve also features a thermal shut-off function that operates in the event of a cold water supply failure at the inlet.

Operating principle
The tempering valve mixes the hot and cold water at the inlet so as to maintain the mixed water at a constant set temperature at the outlet.
A thermostatic element (1) is fully immersed in the mixed water flow (2). It contracts or expands, moving an obturator (3) which controls the passage of hot (4) or cold (5) water at the inlet. If the inlet temperature or pressure changes, the internal element automatically reacts to restore the set temperature at the outlet.
Construction details
Anti-scale materials
The materials used in constructing the tempering valve were selected to eliminate seizing due to limescale deposits. All
functional parts are made using a special anti-scale material with low friction coefficient, which ensures that performance is
maintained over time.
Thermal shut-off
In the event of accidental cold water supply failure, the obturator shuts off the hot water passage, thus preventing the delivery of mixed water. This performance is guaranteed only when there is a minimum temperature difference between the inlet hot water and the outlet mixed water of 15°C.
Temperature adjustment
The temperature is set at the desired value using the control knob with the graduated scale on the valve.
