Danfoss AVTB (fast) Self-Acting Temperature Controller DN 25 20–60 °C 003N8252
Danfoss · HVAC & Refrigeration · Water Regulating Valves
Danfoss AVTB (fast) self-acting temperature controller, OEM P/N 003N8252. 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 25, PN 16, internal thread NPT 1 in. Kvs 5.5 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.
