Data sheet AIQM
Flow controller with integrated
control valve
Combined with an electric actuator the AIQM
controller is a self-acting flow controller with
integrated control valve. The pressure
difference across the control valve is kept
constantly at 0.2 bar.
The controller is primarily used in district
heating systems for circulation water with a
max. temperature of 150
o
C.
AIQM is used together with following actuators:
- AMV 113 / AME 113 with valve closing
safety function, type tested acc. to DIN 32 730
- AME 110 / AMV 310 / AMV 330

Because of the higher valve
opening factor (Y), the noise level
can be insignificantly higher,
depending on the pressure
