Danfoss AVT (fast) thermostatic actuator (self-acting temperature controller), setting range 35 – 70 °C, sensor 255 mm × Ø16 mm, capillary 4 m, sensor connection R 3/4 conic ext. thread acc. DIN 2999, PN 25, for AVQT/AVQMT/AVQM/VG self-acting valves (065-0605) — Datasheet

Danfoss AVT (fast) (065-0605) — self-acting thermostatic actuator / temperature controller, PN 25. The AVT (fast) is a self-acting proportional thermostatic actuator working on the liquid-expansion principle: the temperature sensor, capillary tube and bellows are liquid-filled, and on rising temperature the liquid expands to close the valve. It is type-tested to EN 14597 (TR/TW 700). It comprises a temperature sensor (255 mm × Ø16 mm), a 4 m capillary tube and a bellows element; the sensor is fitted into the pipe via a sensor pocket with connection R 3/4 conic ext. thread acc. DIN 2999. Temperature setting range 35 – 70 °C. Gain Ks 0.7; time constant 30 s; maximum media temperature at the sensor 120 °C; ambient temperature 0–70 °C. Mounts on Danfoss AVQT / AVQMT / AVQM flow-and-temperature controllers and VG(S) valves to add self-acting temperature control in district-heating, hot-water and steam systems. Temperature sensor and impulse (capillary) tube Copper (mat. No. 2.0090); sensor pocket Brass. Type test DIN EN 14597:2005-12 TR (TW)700. Sensor connection R 3/4 conic ext. thread acc. DIN 2999. OEM P/N 065-0605. EAN 5702421544280.

Danfoss AVT (fast) thermostatic actuator with setting range 35 – 70 °C. Sets the temperature on Danfoss AVQT / AVQMT / AVQM flow-and-temperature controllers and VG(S) valves via connection R 3/4 conic ext. thread acc. DIN 2999; the controller/valve body, sensor pocket and tailpieces are ordered separately. Sensor 255 mm × Ø16 mm, capillary 4 m, gain Ks 0.7, time constant 30 s. Confirm the actuator neck matches the valve and that the setting range brackets the required control temperature; maximum media temperature at the sensor 120 °C. Type-tested to EN 14597 (TR/TW 700).
