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