Rotary valves HFE 3
Description
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.
HFE rotary valves can be used in combination with electric actuators AMB 162 and AMB 182.
Features:
•Cast iron body with flange connection
•Lowest leakage in class
•Valve position indicator
•Ergonomic handle
•For mixing and diverting applications
•Flange PN 6 connection
Main data:
•DN 20–150
•kVS 12–400 m3/h
•PN 6
•tmax 110 °C
•3-way
•S characteristic

Installation |
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.
Mixing
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.
Diverting
Note: |
AMB |
|
Install a strainer upstream of the valve |
||
|
||
(e.g. Danfoss FVR/FVF) |
|
|
|
FVR/FVF |
Disposal |
The valve must be dismantled and the elements |
|
sorted into various material groups before |
|
disposal. |
