Danfoss AVTB (PN 16) Temperature Controller

Danfoss AVTB is self-acting temperature controller used to control the water temperature in hot water tanks, heat exchangers, oil preheaters, etc. 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.
The complete AVTB valve has a setting knob, a valve body, a bellows element with capillary tube and a sensor pocket.
The valve is used to control the water temperature in hot-water tanks, heat exchangers, oil preheaters etc.
