Product Description
Danfoss AVPQT (003H6807) — self-acting multi-functional controller combining differential-pressure control, flow limitation and return-temperature limitation, PN 25, DN 15, return-pipe mounting, for district heating and domestic-hot-water substations. The AVPQT combines three self-acting functions in one valve: differential-pressure control, flow (volume) limitation and, via a thermostatic element, temperature limitation of the return. It maintains a constant differential pressure across the integrated flow-limiting valve while the thermostatic actuator throttles on rising return temperature — no auxiliary energy required. kVS 4 m³/h; flow-rate range 0.07 – 2.4 m³/h at Δpb 0.2 bar; differential-pressure setting 0.2 – 1 bar; maximum differential pressure 12 bar; medium temperature 2–150 °C; leakage 0.02% of kVS (IEC 534). Valve body red bronze CuSn5ZnPb (Rg5), valve seat stainless steel 1.4571, valve cone dezincing free brass CuZn36Pb2As, control diaphragm EPDM. Connection external thread G 3/4 A (ISO 228/1).

Compatibility & Fitment
Danfoss AVPQT for DN 15 district-heating substations requiring differential-pressure control, flow limitation and return-temperature limitation in one valve, PN 25, return-pipe mounting. Size by the design flow (range 0.07 – 2.4 m³/h, kVS 4 m³/h) and set the differential-pressure setpoint within 0.2 – 1 bar; the return-temperature limit is set on the thermostatic element. Confirm the connection (external thread G 3/4 A (ISO 228/1)) and pressure class (PN 25) against the pipework. Order the thermostatic sensor/element and impulse tube per the AVPQT installation guide. Maximum differential pressure 12 bar, medium temperature up to 150 °C.
