  • Product Description
  • Detailed parameters
  • The electronic ventilation butterfly valve adopts a unique structural design and is welded with steel plates. The valve has simple structure, light weight, beautiful appearance, long retention, small resistance coefficient and large flow capacity.

    Electronic regulating butterfly valve note:

    1. During installation, the valve flap should be stopped in the closed position.

    2. The opening position should be determined according to the rotation angle of the butterfly plate.

    3. For butterfly valve with bypass valve, the bypass valve should be opened before opening.

    4, should be installed according to the manufacturer's installation instructions, the weight of the butterfly valve, should be set up a solid foundation.

    Electronic ventilation butterfly valve is suitable for low pressure state of water, steam, air, gas, waste gas or other gas containing suspended particles flow, pressure control regulation. It is matched with DCS control system to form the best control (regulation) loop. It is widely used in the process control of chemical industry, metallurgy, electric power, light industry, building materials and other departments.
