  • Improve the efficiency of water pump operation and save energy;

  • Accurate data, KV value tested by testing institute.


Two Way Globe Valve for HVAC Working Principle

Two Way Globe Valve for HVAC Working Principle

The electric two way globe valve is composed of temperature sensor, proportional integral temperature controller and electric regulating valve. The temperature sensor installed in the return pipe transmits the detected temperature signal to the temperature controller, which constantly compares the detected value of the temperature sensor with the set value, and at the same time constantly outputs a signal to control the opening degree of the electric regulating valve connected to the adjustable, finally making the temperature sensor measured The ambient temperature measured by the temperature sensor is kept within the set temperature range.
