Danfoss AVP differential pressure controller, PN 16, DN 25, kVS 8 m³/h, Δp 0.05 – 0.5 bar adjustable, external thread G 1 1/4 A, flow mounting

Danfoss AVP (003H6242) — self-acting differential pressure controller, PN 16, DN 25, for mounting in the flow pipe, 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 8 m³/h; differential-pressure setting range 0.05 – 0.5 bar, adjustable via handle. 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 1 1/4 A (ISO 228/1), via tailpieces (ordered separately). Media: circulation water / glycolic water up to 30% (pH 7–10). OEM P/N 003H6242, EAN 5702421537282.
