Compatibility & Fitment
Fit in the flow line with the sensor in the medium to be controlled; the AVTB closes on rising temperature. Match valve size (DN 15), Kvs (1.9 m³/h) and temperature setting range to the application before ordering. Self-acting — no external power or actuator required. Confirm code and range before ordering.
