AHQM Flow Controller with Integrated Control Valve
Brand: Danfoss
AHQM 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 maximum flow is exceeded.
In combination with Danfoss electrical actuators AMV(E) can be controlled by ECL electronic controllers.
The controllers have a control valve with adjustable flow restrictor, connection neck for electrical actuator, and an actuator with one control diaphragm.
