Danfoss AVPB-F differential pressure controller & flow limiter, PN 16, DN 15, fixed Δp 0.2 bar, 0.06–1.4 m³/h, external thread G ¾ A

Danfoss AVPB-F (003H6411) — self-acting differential pressure control and flow limiter, PN 16, DN 15, for district heating and central heating systems. The AVPB-F closes on rising differential pressure or when the set maximum flow is exceeded, holding a stable differential pressure across the controlled circuit so that connected control valves keep their authority. The controller combines a control valve with an adjustable flow restrictor and an actuator with one control diaphragm (fixed differential-pressure setting, no handle). Differential-pressure setting fixed at 0.2 bar; flow rate 0.06–1.4 m³/h. Maximum differential pressure 12 bar, maximum water temperature 140 °C, cavitation factor z ≥ 0.6. Valve body red bronze Rg 5 (CuSn5ZnPb, DIN 1705 W.no. 2.1096.01), control diaphragm EPDM, valve insert/spindle CrNi steel 1.4404. Connection external thread G ¾ A (ISO 228/1) via tailpieces (ordered separately). Media: water for district/central heating; glycolic water up to 30% resistant to -30 °C. OEM P/N 003H6411. Technical data quoted verbatim from the Danfoss AVPB/AVPB-F PN 16 data sheet and store.danfoss.com (code 003H6411). 2.1096.01); valve insert/spindle CrNi steel 1.4404; control diaphragm EPDM; Pressure rating: PN 16 (max. differential pressure 12 bar); Temperature range: up to 140 °C (heating water); glycolic water resistant to -30 °C; HS code: 8481.80. Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants.
