DANFOSS Danfoss pressure-independent control valve ABQM 4.0 DN15, 65-650 l/h, w/o measuring nipples, 3/4" male thread – 003Z8221

Danfoss Pressure-Independent Balancing and
Control Valve Danfoss AB-QM 4.0
Control valve with linear control
characteristic, independent of the
available pressure and flow
setting. For control with
consistently highest valve authority
100% at all settings. Modulates
the flow via an actuator,
regardless of the setting below 1%
of the set flow,
control ratio 1:1000. Prepared for
the installation of an actuator.
Equal percentage control characteristic can be switched
via motor-driven Danfoss actuator (AME,
NovoCon(R)). AB-QM 4.0,
together with the
intelligent NovoCon(R) actuator,
enables the integration of perfect hydraulics into
modern building automation,
Building Technology 4.0.
Also usable as a flow regulator for
hydraulic balancing without an actuator.
The flow is set directly at the valve;
the setting is visible at all times
from 2 sides, even with the actuator mounted. Maximum
flow indicated on the valve.
Contamination-resistant valve
design thanks to polymer cone.
AB-QM 4.0 is intended for installation in
the supply or return with integrated
shut-off closing up to 16 bar.
Versions with internal or external
thread as well as with or without measuring nipples
for precise flow checking and
pump optimization.
