Thermostatic operated water valves are used for proportional regulation of flow quantity, depending on the setting and the sensor temperature.The Danfoss range of thermostatic operated water valves includes a series of products for both refrigeration and heating regulation. The valves are self-acting, i.e. they operate without the supply of auxiliary energy such as electricity or compressed air. The required temperature is maintained constant without unnecessary use of: cooling water in cooling systems and hot water or steam in heating systems The operating economy and efficiency are maximized.
