Danfoss AIPB-F Operating instructions

Type
Operating instructions

Danfoss AIPB-F is a differential pressure controller with flow limitation, designed for use in heating and cooling systems. It is equipped with a flow limitation function, which allows you to set a maximum flow rate through the valve. This can be useful for preventing system damage or noise in the event of high flow rates.

The AIPB-F is also equipped with a built-in pressure sensor, which allows you to monitor the pressure drop across the valve. This information can be used to diagnose system problems or to optimize the system's performance.

Installation
Clean pipeline system
prior to assembly.
The installation of a
strainer in front of the
controller is strongly
recommended.
The installation of shut-off
units in front of the
strainer and behind the
valve is recommended.
Install pressure indicators
in front of and behind the
system part to be
controlled.

installed in the return
pipe.
Up to a medium
temperature of 100 °C,
the controllers may be
installed in any position.
For higher temperatures,
the actuator must be
installed in a downward
hanging position.

pipelines are not
permitted.
The flow direction
indicated on the rating
plate must be observed.

Achtung:
Das Ventil mit
angeschraubten
Anschweißenden darf in
der Rohrleitung nur
angeheftet werden.
Das Einschweißen der
Anschweißenden ist nur
ohne Ventil und
Dichtungen zulässig.
Bei Nichtbeachtung
zerstören die hohen
Schweißtemperaturen die
Dichtungen des Ventils.
Steuerleitungsanschluss
Es wird empfohlen, den
Steuerleitungsanschluss
an der Rohrleitung
waagrecht anzubringen.
Verschmutzungen in der
Steuerleitung und mög-
liche Funktionsstörungen
des Reglers werden
dadurch vermieden.
Die Steuerleitung (Cu-
Rohr Ø 6x1) ist am (+)
Anschluss des Antriebs
und vor der zu regelnden
Anlagenstrecke
anzuschließen.
Der Regler AIPB-F ist nur
für den Einbau im
Rücklauf vorgesehen.
Caution:
The valve with mounted
screwed welded ends
must only be pinned to
the pipeline.
The welded ends must
only be welded without
the valve and seals!
If these instructions are
not complied with, high
welding temperatures
may destroy the seals of
the valve.
Control line connection
We recommend to install
the impulse tube
connection to the pipeline
in an upright or horizontal
position.
This avoids dirt in the
impulse tube and
possible malfunction of
the controller.
Connect the (+)impulse
tube (Cu pipe Ø 6 x 1) to
the (+)connection of the
actuator and in front of the
system part to be
controlled.
The controller AIPB-F is
only to be installed in the
return line.

Danfoss AIPB-F Operating instructions

Type
Operating instructions

Danfoss AIPB-F is a differential pressure controller with flow limitation, designed for use in heating and cooling systems. It is equipped with a flow limitation function, which allows you to set a maximum flow rate through the valve. This can be useful for preventing system damage or noise in the event of high flow rates.

The AIPB-F is also equipped with a built-in pressure sensor, which allows you to monitor the pressure drop across the valve. This information can be used to diagnose system problems or to optimize the system's performance.
