Return Temperature Limiter Type FJVR - Sensor
and Valve Body
Application
The return limiter type FJVR automatically controls the return temperature from radiators, convectors and floor heating pipes.
In ventilation systems FJVR ensures a certain minimal circulation in the pipe system up to the heat exchanger.
FJVR is a self-acting P-band regulator, used in 2- pipe systems with pump.
Setting can be limited and locked.
FJVR valve bodies are nickel-plated.

1)Outlet connection is prepared for Danfoss compression fittings.
2)The kv-value indicates the water flow (Q) in m³/h at a pressure drop (Δp) across the valve of 1 bar.
3)The max. differential pressure indicates the limit for an optimal valve performance. To ensure quiet operation it is recommended to choose a pump which provides the correct pressure to circulate the required flow of water. In most systems a differential pressure of 0.1-0.3 bar is sufficient. The differential pressure may be reduced by using Danfoss differential pressure controls.
