The Danfoss AVTA two-way thermostatic valve is used for proportional regulation of the cooling medium flow depending on the set temperature on the sensor. The valve is self-acting, meaning it operates without the use of electricity or compressed air. It is used in both closed and waste cooling systems. It is designed for water, air, oil, and inert gases. Slow valve closing with a low level of pressure surges.

The valve is actively resistant to impurities the design based on force compensation prevents particles from entering the valve and dirt from adhering to its opening. However, if impurities do settle in the valve, the sensor simply detects the need for increased flow, and the valve opens more to allow increased water flow, which releases the impurities.

The sensor with a universal filling contains a mixture of liquid and gas, with the surface of the liquid (control point) always located inside the sensor. It can be mounted in a place cooler or warmer than the valve installation site.

Operational economy and efficiency with long valve life is provided by Danfoss quality.
