Solutions for Constant Flow Systems

Danfoss oﬀers a range of solutions using both manual and automatic balancing

valves, using a combination of the LENO

MSV-O and MSV-BD valves can provide

ease of installation and balancing. In the MSV-O valve, the ﬂow is measured over

a ﬁxed venturi oriﬁce, providing very fast and accurate measurement. The MSV-O

and MSV-F2 valves can then be adjusted to provide the required ﬂow rates.

In order to reduce installation and commissioning costs, the ABQM valve can be

used to good eﬀect as a constant ﬂow regulator (CFR). The setting of the ﬂow

is simply a case of calculating the required ﬂow, selecting a valve which covers

the ﬂow rate you require and setting the valve (desired ﬂow/max ﬂow x 100 =

setting). This means no commissioning or measurement is needed, however the

ABQM valves do have nipples for diﬀerential pressure recording and veriﬁcation

purposes.

Solutions for Variable Flow Systems

Variable ﬂow systems are perfectly suited to automatic balancing valve solutions

(ASV), or by using the ABQM, combined with an actuator (see pages 46 to 49) to

act as a ﬂow regulator and control valve in one. As with the constant ﬂow system,

when using an ABQM the need for additional valves is removed, and setting up

for a required ﬂow is simple using the built in scale on the valve.
