Rotary valves HFE 3
Description
Ordering
Danfoss HFE rotary valves are primarily designed
for regulation of flow temperature in heating
systems where a certain leakage can be accepted
and where a defined control characteristic is not
required.

Valve mounting
Before valve mounting pipes have to be cleaned
and free from abrasion. Mechanical loads on
valve body caused by the pipes are not allowed.
It is recommended to install a strainer into
application to avoid damaging controlling
components.
Connection
HFE 3 can be used as a mixing valve, diverting
valve and in connection with heat exchangers
where a certain leakage can be accepted.
Note:
Install a strainer upstream of the valve
(e.g. Danfoss FVR/FVF)

Disposal
The valve must be dismantled and the elements
sorted into various material groups before
disposal.
