The Danfoss FJV valve ensures that the return water temperature in the return line is sufficiently cooled to the desired value before it flows back into the district heating system. The regulator closes as the temperature rises.

The regulator consists of a control valve, a thermostatic actuator, and a head that allows temperature adjustment. The thermostatic actuator is made up of a bellows. Installation is possible in both supply and return pipes.

The operational economy and efficiency with the long lifespan of the valve are provided by the quality of the Danfoss brand.

Application

• For regulating the return water temperature from the water tank in systems directly connected to district heating systems.
