Rotary valves HRB 3, HRB 4
Description
Danfoss HRB 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.
HRB rotary valves can be used in combination
with electric actuators AMB 162 and AMB 182.
Features:
• Lowest leakage in class
• Unique position indicator
(visible also when actuator in mounted)
• Ergonomic handle
• Easy installation
• For mixing and diverting applications
• Internal thread connection

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
HRB 3 can be used as a mixing valve, diverting
valve and in connection with heat exchangers
where a certain leakage can be accepted.
HRB 4 operates according to the double shunt
principle i.e. the water from the boiler is mixed
with a certain portion of the water in the return.
In this way the water which goes to the boiler
reaches a higher return temperature than by
using 3-way valves. This means that the risk of
corrosion in oil and solid fuel boilers is reduced.
Disposal

Note:
Insta ll a strainer up stream of the va lve
(e.g. Dan foss FVR/FV F)
The valve must be dismantled and the elements
sorted into various material groups before
disposal.

Application principles
HRB 3
The reverse function is obtained by turning the actuator's direction of rotation and the valve's sign.
