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.

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.

During construction, the heat can be controlled
by turning the slotted screw in the valve cap, prior to fitting the element.
