AVQML (PN25)

AVQML is a self-acting flow controller with integrated control valve primarily for use in district heating systems or in secondary district heating systems as well. The controller closes when set max. flow is exceeded.
In combination with Danfoss electrical actuators AMV(E) can be controlled by ECL electronic controllers.

AVQML has a control valve with adjustable flow restrictor, connection neck for electrical actuator, and an actuator with one control diaphragm.


Controllers are used together with Danfoss electrical actuators or with self-acting thermostat:

• AMV 150
  
• AMV(E) 10
  
• AMV(E) 13 with spring return function
  
• AMV(E) 130 (H)*
  
• AMV(E) 140 (H)*
  
• QTL thermostat
