AVTA

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
  • Hot water or steam in heating systems
The operating economy and efficiency are maximized.
AVTA SS for aggressive media:
A valve body in stainless steel means that the valve can be used for aggressive media in such applications as the marine sector and the chemical industry.

Features and benefits

  • Insensitive to dirt
  • Insensitive to water pressure
  • Needs no power supply – self acting
  • Opens on rising sensor temperature
  • Differential pressure: 0 – 10 bar
  • Maximum working pressure (PS): 16 bar
  • Maximum test pressure: 25 bar
  • Maximum pressure on sensor: 25 bar and the regulation range is defined for the point at which the valve begins to open
  • Stainless steel version available and cooling media temperature range: -25 – 130 °C
  • The valves are pressure-relieved, i.e. degree of opening is not affected by differential pressure Δp (pressure drop) and ethylene glycol as a cooling media up to 40%
