AVTA Thermo. Operated Water Valve

Brand: Danfoss

Thermo. operated water valves are used for proportional regulation of flow quantity, depending on the setting and the sensor temperature.

The Danfoss range of thermo. 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.
Features
  • Insensitive to dirt
  • Insensitive to water pressure
  • Needs no power supply – self acting
  • Opens on rising sensor temperature
  • Differential pressure: 0 to 145 psi
  • Maximum working pressure (MWP): 232 psi
  • Maximum test pressure: 365 psi
  • Maximum pressure on sensor: 365 psi
  • Stainless steel version available
  • The valves are pressure-relieved, i.e. the degree of opening is not affected by differential pressure Δp (pressure drop)
  • The regulation range is defined for the point at which the valve begins to open 
  • Cooling media temperature range: -13° to 266° F
  • Ethylene glycol as a cooling media up to 40%
