Danfoss AVTB (fast) Self-Acting Temperature Controller DN 15 20–60 °C 003N8229
Danfoss · HVAC & Refrigeration · Water Regulating Valves
Danfoss AVTB (fast) self-acting temperature controller, OEM P/N 003N8229. Proportional self-acting controller that regulates water temperature in district heating and cooling circuits; a remote 2 m capillary and charged sensor (Ø 9.5 mm × 180 mm) sense the medium temperature and throttle the valve, with a 3-second reaction time (fast version). DN 15, PN 16, internal thread Rp 1/2 in (ISO 7/1). Kvs 1.9 m³/h; temperature setting range 20 – 60 °C, linear characteristic. Brass body (CuZn40Pb2), NBR valve cone, Cr Ni steel valve seat, copper impulse tube and sensor. Max differential pressure 10 bar; media temperature 2 – 130 °C, max sensor temperature 90 °C. Approved to ETA VA 1.54/18952. Confirm the setting range and code against the datasheet before ordering.
