As a device for opening, closing and regulating ventilation and dust removal pipes, ventilation butterfly valves are suitable for ventilation, dust removal and environmental protection systems in metallurgy, mining, cement, chemical industry, power generation and other industries.
The ventilation butterfly valve is made of the same material as the valve body and is processed into a sealing ring. Its applicable temperature depends on the material selection of the valve body, and the nominal pressure is ≤0.6MPa. It is generally suitable for ventilation and media flow adjustment in industrial, metallurgical, environmental protection and other pipelines.
Its main features are:
1. Novel and reasonable design, unique structure, light weight, quick opening and closing.
2. The operating torque is small, and the operation is convenient, labor-saving and dexterous.
3. Appropriate materials should be used to meet the requirements of low, medium and high medium temperatures and corrosive media.
