The Danfoss AVTB thermostatic valve is a self-acting temperature controller used to control the water temperature in hot water tanks, heat exchangers, oil preheaters, etc. The valve is self-acting, ie. it operates without the use of electricity or compressed air. The AVTB controller closes on rising temperature.

The controller has a control valve, thermostatic actuator and handle for temperature setting. Thermostatic actuator consist of a bellows, capillary tube and sensor.

Danfoss quality ensures operational economy and efficiency with long valve life.
