DANFOSS Danfoss pressure independent control valve ABQM 4.0 DN20, 110-1100 l/h, w/o measuring ports 1" male thread – 003Z8223

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,
turndown ratio 1:1000. Prepared for
the installation of an actuator.
Equal-percentage control characteristic via
motorized Danfoss actuator (AME,
NovoCon(R)) switchable. AB-QM 4.0
together with the
intelligent actuator NovoCon(R)
enables the integration of perfect hydraulics into
modern building automation,
Building Technology 4.0.
Can also be used as a flow controller for
hydraulic balancing without an actuator.
The flow is set directly on the valve,
visibility of the setting at all times
from 2 sides, also possible with mounted
actuator. Maximum
flow marked on the valve.
Contamination-resistant valve
construction due to polymer cone.
AB-QM 4.0 is intended for installation in the
flow or return line for integrated
shut-off closing up to 16 bar.
Versions with internal or external
thread as well as with or without measuring ports
for precise flow measurement and
pump optimization.
