Thermostatic valves - the robust choice

Danfoss thermostatically operated valves are a simple and reliable control solution requiring neither electricity nor control air. The range of thermostatic valves includes a series of industrial products for both cooling and heating controls. The valves are self-acting, i.e. they operate without the supply of auxiliary energy such as electricity or compressed air.

Thermostatic valve technology

Danfoss thermostatic valves are used for the infinite, proportional regulation of flow quantity depending on the setting and the sensor temperature. 

Because the valves constantly match flow quantity to demand, they are especially efficient for temperature control. 

The required temperature is maintained with no over-consumption of cooling water in cooling systems.


Applications of thermostatic valves

Danfoss thermostatic valves are a simple and reliable way to control the temperature in cooling applications. They are typically used in:

  • Hydraulic systems
  • Bio-mass boilers
  • Injection moulding machines
  • Compressors
  • Vacuum pumps
  • Dry-cleaning machines
  • Distillation plants
  • Other machinery using liquid cooling
  • Steam boiler application
  • Autoclaves

Features and benefits

    AVTA thermostatically operated water valves

    AVTA thermostatic operated water valves are used for proportional regulation of water flow quantity in refrigeration plants with water-cooled condensers for condensing pressure regulation purposes. AVTA water regulating valves give modulating regulation of the condensing pressure and so maintain it constant during operation.
