The ventilation butterfly valve is a two-way opening and closing and regulating device for ventilation and dust removal pipelines. It is a simple regulating valve and can also be used for the switch control of low-pressure pipeline media. The ventilation butterfly valve is used in dusty cold air or hot air gas pipelines in ventilation and environmental protection projects in the chemical, building materials, power stations, glass and other industries as a pipeline control device for regulating the flow or cutting off the gas medium.

The ventilation butterfly valve is divided into manual and electric transmission. The actuator can be driven by an electric motor or a turbine to make the butterfly plate rotate freely within a 90° range to achieve the purpose of opening and closing or regulating the medium flow.

1. The advantage of the ventilation butterfly valve is its simple structure, so it has better structural performance, small size, light weight and low cost.

2. The advantage of the ventilation butterfly valve is its small opening and closing torque, so it has better performance of small opening and closing torque.

3. The advantage of the ventilation butterfly valve is its good sealing performance, so it has better sealing performance.

4. The advantage of the ventilation butterfly valve is its small fluid resistance, so it has better performance of small fluid resistance
