FJV Return Temperature Limiter
Brand: DanfossThe FJV ensures that return water is cooled to required temperature before it flows back to the district heating plant.
Controller closes on rising temperature. The controller has a control valve, thermostatic actuator and handle for temperature setting. Thermostatic actuator consist of a bellows only.
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
