CALEFFI VALVES

Thermostatic valves are typically used to regulate the fluid to radiators in heating systems. Combined with a thermostatic, electrothermal or electronic control They keep the room temperature of the room in which they are installed constant at the set value. This prevents undesirable temperature increases and results in substantial energy savings.

These valves are equipped with a special shank with a rubber hydraulic seal, which allows them to be connected to the radiator quickly and safely, without the aid of any other sealing medium.

Caleffi constantly strives to pursue coverage of the most important standards suggested by ISO standards.
