Danfoss AVQM-WE (003H7090) — self-acting flow 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, PN 25, DN 50, 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. Flow range 0.8 - 14 m³/h; Kvs 25 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 Ductile iron EN-GJS-400-18-LT (GGG 40.3); stainless-steel seat/cone; EPDM control diaphragm. Connection Flange DN 50 (EN 1092-2). 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 are ordered separately. OEM P/N 003H7090.
