Danfoss AVQMT-WE (003H7084) — self-acting flow and temperature controller with integrated, pressure-independent motorized control valve (PICV); holds the differential pressure across the built-in flow restrictor constant so the electric actuator stem position sets flow independent of system pressure; limits the flow to the set maximum and closes on rising media temperature, PN 25, DN 15, for district heating and cooling systems. Because the built-in differential-pressure controller keeps the pressure drop across the flow restrictor constant, the flow becomes pressure-independent: the position of the separately ordered Danfoss AMV(E) electric actuator directly sets the flow, and the valve limits the flow to the set maximum and closes on rising media temperature via an AVT thermostatic actuator or STM safety temperature monitor fitted to the second connection neck. Flow range 0.07 - 1.6 m³/h; Kvs 2.5 m³/h; flow-restrictor differential pressure (Δpb) 0.2 bar; maximum differential pressure 16 bar; media temperature 2–150 °C; seat leakage 0.05 % Kvs (IEC 60534). Valve body Dezincification-resistant brass; stainless-steel seat/cone; EPDM control diaphragm. Connection External thread G 3/4 A (ISO 228/1), via tailpieces. Mounting version Free. Permissible media: district-heating/cooling circulation water (glycolic water up to 30 %), pH 7–10. The controller is delivered completely assembled, including the impulse tube between valve and actuator; the AMV(E) electric actuator and the AVT/STM thermostatic actuator are ordered separately.

Danfoss AVQMT-WE for DN 15 district-heating/cooling combined flow limiting, pressure-independent flow control and temperature limiting at PN 25. Set the maximum flow within 0.07 - 1.6 m³/h using the adjustable flow restrictor (Kvs 2.5 m³/h); because control is pressure-independent, the flow follows the electric actuator position regardless of Δp swings (up to 16 bar). Fit a Danfoss AMV(E) electric actuator (ordered separately), controllable by an ECL electronic controller. For temperature limiting, fit a Danfoss AVT thermostatic actuator or an STM safety temperature monitor on the second neck (ordered separately). Confirm the connection (External thread G 3/4 A (ISO 228/1), via tailpieces) and pressure class (PN 25) match the pipework; order the matching tailpiece/union-nut set separately. Media temperature up to 150 °C.
