Product Description
Danfoss AVP (003H6318) — self-acting differential pressure controller, PN 25, DN 20, for district heating and central heating systems. The AVP closes on rising differential pressure, holding a stable differential pressure across the controlled circuit so that connected control valves keep their authority. It consists of a control valve and an actuator with one control diaphragm and a handle for differential-pressure setting. Unlike the AVPB, the AVP is a differential-pressure controller only (no integrated flow limiter). kVS 6.3 m³/h; differential-pressure setting range 0.2 – 1 bar, adjustable via handle. Maximum differential pressure 20 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 1 A (ISO 228/1), via tailpieces (ordered separately). Media: circulation water / glycolic water up to 30% (pH 7–10). OEM P/N 003H6318, EAN 5702421538159.

Compatibility & Fitment
Danfoss AVP for DN 20 district-heating or central-heating circuits, PN 25. Size by the branch design flow (kVS 6.3 m³/h) and set the differential-pressure setpoint within 0.2 – 1 bar. Confirm the connection (external thread G 1 A (ISO 228/1)) and pressure class (PN 25) match the pipework; order the matching tailpiece/union-nut set and impulse tube separately. For combined differential-pressure control and flow limiting use the AVPB/AVPQ instead. Maximum differential pressure 20 bar, medium temperature up to 150 °C.
