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 oers the following versions:
• FHV-R provides temperature control of under­oor 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 simplies 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.
