Return Temperature Limiter Type FJVR - Sensor and Valve Body
Application
System
Data and Ordering
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.

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.

Design
Mounting
The return temperature limiter includes a ther­mo-static element type FJVR and a valve body type FJVR 10. The element and the valve body are ordered sep­arately. The gland of the valve can be exchanged without draining down system.

Setting
FJVR is mounted in the radiator outlet. The valve and sensor can be fitted in any position as long as flow direction is observed.
