AVQM is a self-acting flow controller with integrated control valve developed for the use in district heating / cooling systems. The controller prevents flow to exceed set max flow. In a combination with electrical actuators AMV(E) and ECL electronic controllers the flow and temperature can be controlled to achieve highest energy savings. AVQM has a control valve with adjustable flow limiter, connection neck for electrical actuator and a pressure actuator with one control diaphragm.Controllers are 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(E) 23 SU (spring up)- AMV 20 SL / AMV 23 SL / AMV 30 SL with stroke limitation1) AMV 150 / AMV(E) 10 / AMV(E) 13 can be combined with DN 15 controller only.AVQM combined with AMV(E) 13, AMV(E) 23 (SL) or AMV(E) 33 (SL) has been approved according to DIN EN 14597.
