The Electric Ventilation Butterfly Valve is made of the same material as the valve body and is processed into a sealing pattern. Its operating temperature and corrosion resistance depend on the material selection of the valve body. The nominal pressure is <0.6MPa, and its leakage is controlled within 2% of the maximum flow. It is used in industrial, metallurgical, environmental protection and other pipelines for ventilation and regulating medium flow. It has the characteristics of simple structure, light weight, small operating torque, rapid opening and closing, flexible movement, large circulation capacity and high adjustment accuracy. It is suitable for the regulation and control of flue gas, powder, air or fluids containing suspended particles and thick and slurry fluids.
