AVQT / AVQMT
AVQT is a self-acting flow and temperature controller primarily for use in district heating systems. The controller closes on rising temperature or when set max. flow is reached.
AVQMT is a self-acting flow and temperature controller with integrated control valve primarily for use in district heating systems. The controller closes on rising temperature or when set max. flow is reached.
AVQT controller can be combined with AVT or STM thermostatic actuators.
AVQMT controller can be combined with Danfoss electrical actuators AMV(E) (and controlled by ECL electronic controllers) and with AVT or STM thermostatic actuators.
The controllers AVQT and AVQMT have a control valve with adjustable flow restrictor, connection neck for thermostat, connection neck for electrical actuator (AVQMT only), and a pressure actuator with one control diaphragm.
AVQMT is used together with Danfoss electrical actuators:
- AMV 150 1)
- AMV(E) 10 1) / AMV(E) 20 / AMV(E) 30
- AMV(E) 13 1) / AMV(E) 23 / AMV(E) 33 with spring return function
- AMV 20 SL / AMV 23 SL / AMV 30 SL with stroke limitation
1) AMV 150 / AMV(E) 10 / AMV(E) 13 can be combined with DN 15 controller only.
AVQMT controllers combined with AMV(E) 13, AMV(E) 23(SL) or AMV(E) 33 electrical actuators are type-tested acc. to EN 14597.
AVQT and AVQMT controllers combined with AVT or STM thermostatic actuators are type-tested acc. to EN 14597.
Controllers combined with STM thermostatic actuators protect systems against exceeding temperatures.
