The Danfoss FJVR RTL DN 15 direct set is used to limit the return temperature in heating systems. It is suitable, for example, for underfloor heating connected to a common source or for circuits where it is necessary to control the temperature of the returning medium. The set includes an FJVR valve and an FJVR sensor with an integrated sensor.

The FJVR valve automatically regulates the water flow based on the set return temperature. Thanks to its direct design, it is suitable for standard pipe installations. Limiting the temperature in the return increases the system's efficiency and extends the lifespan of the boiler or exchanger.
