FHV Regulating Valve
Application
System Lay-outs
FHV control valves are ideally suited for controlling
the temperature of individual under-oor heated
rooms and for systems using oor heating in
conjunction with radiators.
Danfoss oers the following versions:
• FHV-R provides temperature control of underoor heating circuits, using a return temperature limiting valve tted with a type FJVR
sensor element.
• FHV-A enables oor temperature control via a
presettable thermostatic valve tted with a
type RA 2000 sensor element.
FHV-A
Floor heating system, heating circuit with FHV-A in
ow.
FHV control valves are exible to use and easy to
install in the oor heating circuit.
With the FHV-A , the integrated presetting
simplies hydraulic balancing of the system.
Connections to the ¾” external thread are made
with Danfoss compression connectors.
Note!
If using the FHV-A for room temperature control, the
ow temperature should not be permitted to exceed
the maximum recommended by the oor heating
supplier. When the FHV-R is used for controlling oor
heating, the heated oor area should not be greater
than 10 m².
FHV-R
Floor temperature control of mixed system, heating
circuit with FHV-R in return.

Presetting
Capacity Diagram
Danfoss presettable valve bodies incorporate
easy-to-use adjustment rings with clearly
engraved setting markers scaled from 1 - 7 and N.
The preset level can be selected in 0.5 increments
between 1 and 7 (see capacity diagram for ow
rates). At setting N the valve is fully open
(ushing option).
Setting values can be set quickly and precisely
without any tools:
1. Remove protective cap or sensor element.
2. Lift setting ring.
3. Turn anti-clockwise to the desired engraved
setting value.
4. Allow setting ring to spring back into position.

Installation
FHV valves are equally suited for installation
in solid and partition walls.
All connections are made within the wall
enclosure box.
Sensor and cover are simply plugged on. An optional installation tool with spirit level
(code no. 003L1338) is available to make
assembly extra easy and reliable.
