Product Description
Danfoss AVQM (003H6736) — self-acting flow controller with integrated control valve, PN 16, DN 15, for district heating and cooling systems. The AVQM holds the flow rate constant and limits it to the set maximum; the integrated control valve accepts a Danfoss AMV(E) electric actuator for combined flow and temperature control. It comprises a control valve with adjustable flow limiter, a connection neck for the electric actuator and a pressure actuator with one control diaphragm. Flow range 0.07–1.6 m³/h; flow-restrictor differential pressure 0.2 bar; Kvs 2.5 m³/h. Maximum differential-pressure range 12 bar; media temperature 2–150 °C; cavitation factor z ≥ 0.6; seat leakage 0.02 % Kvs (IEC 60534). Valve body Red bronze CuSn5ZnPb (Rg5); valve cone Dezincing free brass CuZn36Pb2As; seat Stainless steel, mat. 1.4571; control diaphragm EPDM. 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. OEM P/N 003H6736. Technical data quoted verbatim from store.danfoss.com (code 003H6736) and the Danfoss AVQM (PN 16) data sheet. 1.4571; control diaphragm EPDM; Pressure rating: PN 16 (max. differential-pressure range 12 bar); Temperature range: 2 to 150 °C (district heating/cooling water); HS code: 8481.80. Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants. No.

Compatibility & Fitment
Danfoss AVQM for DN 15 district-heating/cooling flow (PICV) control at PN 16. Set the maximum flow within 0.07–1.6 m³/h using the adjustable flow restrictor (Kvs 2.5 m³/h). The integrated control valve accepts a Danfoss AMV(E) actuator for combined flow/temperature control (ordered separately). Confirm the connection (External thread G 3/4 A (ISO 228/1), via tailpieces) and pressure class (PN 16) match the pipework; order the matching tailpiece/union-nut set separately. Maximum differential-pressure range 12 bar, media temperature up to 150 °C.
