FJV

FJV is self-acting temperature controller used to control:

• return water temperature from hot water tanks in direct connected district heating systems,
  
• return water temperature in district heating systems with mixing loop.
  
  

The FJV ensures that return water is cooled to required temperature before it flows back to the district heating plant. Controller closes on rising temperature.
