Caleffi 2-way zone valve G 1/2 cod. 676040

Zone valves are used to control the heat transfer fluid in air conditioning systems.

Coupled with an electrothermal control and placed under the management of a room thermostat, they allow automatic interception of the part of the hydraulic circuit in which they are inserted.

They are characterized by limited flow coefficient values, so they are typically installed to control small areas or directly on the terminals.
