Ventilation butterfly valve is used in chemical industry, building materials, power station, glass and other industries, as well as in the dust containing cold air or hot air gas pipeline of environmental protection engineering.
The ventilation butterfly valve is used as a pipeline control device to regulate the flow or cut off the gas medium. This kind of valve should be installed horizontally in the pipeline.
1. Ventilation Butterfly Valve is designed and manufactured with a new structural form of welding center line disc plate and short structural steel plate. It has the advantages of compact structure, light weight, easy installation, small flow resistance, large flow volume, avoiding the influence of high temperature expansion, and easy operation.
2. There is no connecting rod, bolt, etc. in it, so ventilation butterfly valve has long service life.
3. Ventilation butterfly valve can be installed in multiple positions, and is not affected by the flow direction of media.
