The structure principle and application of electric ventilated butterfly valve

The electric ventilated butterfly valve is designed and manufactured with a new structural form, and is welded with a Central Line plate and a short structural steel plate. Compact structure, light weight, easy installation, small flow resistance, large circulation, avoid the influence of high temperature expansion, light operation. No connecting rod, bolt, etc., reliable work, long service life. It can be installed at multiple stations without being affected by the flow of media.

The butterfly valve is made of the same material as the valve body into a sealing ring and is driven by electric or pneumatic drive. Its applicable temperature depends on the material selection of the valve body, called pressure ≤0.6MPa, generally suitable for industrial, metallurgical, environmental protection and other pipelines that regulate the flow of ventilation media.

Electric ventilation butterfly valve is mainly used in metallurgy, chemical industry, building materials, power station, glass and other industries in the ventilation and environmental protection engineering dust cold air or hot air gas pipeline, as a gas medium to adjust the flow or cut off the device.
