The AVTA thermo. operated water valve is used for proportional regulation of flow quantity, depending on the setting and the sensor temperature. The valves are self-acting, i.e. they operate without the supply of auxiliary energy such as electricity or compressed air. It is used in closed and waste cooling systems. It is designed for water, air, oil and inert gases. Slow closing of the valve with low level of pressure surges.

The valve is actively insensitive to dirt - the force-compensated design prevents particles from entering the valve and adhering dirt to its opening. However, if dirt is still deposited in the valve, the sensor simply detects the need for increased flow and the valve opens more to allow increased water flow to release the dirt.

Sensor with universal cartridge contains a a mix of liquid and gas where the liquid surface (regulating point) is always inside the sensor. Can be installed in a place where it is either colder or warmer than the valve

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