AHQM (DN 15-50)
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 max. 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.
Controllers are used together with Danfoss electrical actuators:
- DN 15-32 with
- AMV(E) 10
- AMV(E) 13 with spring return function
- AMV(E) 130, AMV(E) 140
- AMV(E) 130H, AMV(E) 140H with manual operation
- DN 40-50 with
- AMV(E) 435
- AMV(E) 25 SD spring return function (spring down)
AHQM, DN 15-32 combined with AMV(E) 13 has been approved according to DIN EN 14597.
Features and benefits
- Self-acting controller automatically closes when the set maximum flow is exceeded.
- Enables electronic control for energy savings with Danfoss actuators and controllers.
- Designed for reliable flow limitation in primary and secondary district heating systems.
