The Danfoss AVTB thermostatic valve is a direct acting temperature regulator used to regulate the water temperature in hot water storage 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 at increasing temperature.

The regulator has a regulator valve, a thermostatic head and a temperature setting lever. The thermostatic actuator consists of a bellows, a capillary tube and a sensor.

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