FHV regulating valve
Temperature control of individual
floor-heated rooms or
mixed floor-heating/radiator systems
Application
FHV-A
FHV-R
FHV control valves are ideally suited to the temperature control of individual under-floor heated
rooms and for systems using floor-heating in conjunction with radiators. Danfoss offers the following
versions:
- the FHV-R provides temperature control of underfloor heating circuits, using a return temperature
limiting valve fitted with a type FJVR sensor element
- the FHV-A enables floor temperature control via a
pre-settable thermostatic valve fitted with a type RA
2000 sensor element
Ordering and technical data
Note: If using the FHV-A for room temperature control, the flow temperature should not be permitted to
exceed the maximum recommended by the floor
heating supplier. When the FHV-R is used for controlling floor heating, the heated floor area should
not be greater than 10 m2.
FHV control valves are flexible to use and can be
simply and easily installed in the floor heating circuit.
With the FHV-A, its integral pre-setting simplifies
hydraulic balancing of the system. Connections to
the 3/4" external thread are made with Danfoss
compression connectors.
FHV-R. Set includes wall enclosure box, cover and valve (return temperature limiter). An FJVR sensor element is required for controlling the return temperature.

Danfoss pre-settable valve bodies incorporate easy
setting adjustment rings with clearly engraved setting
markers scaled from 1 - 7 and N. Setting values can
be set quickly and precisely, without the need for
tools, as follows:
- Remove protective cap or sensor element
- Lift setting ring
- Turn anti-clockwise to the desired engraved setting
value
- Allow setting ring to spring back into position
The preset level can be selected in 0.5 increments
between 1 and 7 (see chart on page 3 for flow rates).
At setting N the valve is fully open (flushing option).

FHV valves are equally suitable for installation in
solid or partition walls. To assist in the fitting of
FHV control valves, we offer a compact customised
valve enclosure wall box that can be fitted and fastened easily into a shallow recess in any type of
wall.
All connections are made within the enclosure. The
Danfoss sensor is simply plugged on.
An optional installation aid, incorporating a spirit
level, is available to make assembly extra easy and
reliable.
