Ventilation butterfly valve is made of the same material as the valve body into a sealing ring, using manual, pneumatic, electric and other transmission methods. The applicable temperature depends on the material selected for the valve body, and the nominal pressure is ≤0.6MPa. It is generally suitable for industrial, metallurgical, environmental protection and other pipes for ventilation and regulating medium flow.
Ventilation butterfly valve is a type of valve that uses a circular butterfly plate as the opening and closing part and rotates with the valve stem to open, close and adjust the fluid channel.
Ventilation butterfly valve has the characteristics of simple structure, small size, light weight, low material consumption, small installation size, fast switching, 90 ° reciprocating rotation, and small driving torque. It is used to cut off, connect, and adjust the medium in the pipeline. Good fluid control characteristics and closed sealing performance.
Ventilation butterfly valve is used in ventilation, environmental protection engineering, dusty cold air or hot air gas pipelines in chemical, building materials, power stations, glass and other industries, as a pipeline control device for regulating or cutting off the flow of gaseous media. This type of valve should generally be installed horizontally in the pipeline.
