Electric ventilation butterfly valve is specially used in all kinds of air, including dust gas, high temperature flue gas and other pipes, as the control of gas flow or switch off, and different materials are selected to meet the different medium temperatures of low, medium and high, and corrosive media. Generally, the temperature is between – 20 ~ 425 ℃, and the pressure is less than 0.6MPa. It has the advantages of small operating torque and convenient operation, Long service life.

The electric ventilation regulating butterfly valve can be operated by inputting the control signal (4 ~ 20mADC or 1 ~ 5VDC) and relevant power supply to meet the needs of pipeline operation. The ventilation butterfly valve adopts a new structure of central line type disc plate and short structure steel plate welding, which has the characteristics of compact structure, light weight, easy installation, small flow resistance, large flow volume and easy operation. It is widely used in building materials, metallurgy, automobile, electric power, ventilation, environmental protection engineering and other industries.
