Product introduction
The flue butterfly valve is processed into a sealing ring with the same material as the valve body. Its applicable temperature depends on the material selection of the valve body. Generally, the nominal pressure is less than 0.6MPa. It is generally suitable for power plant, metallurgy and environmental protection as the medium for cutting off and regulating hot air.
Purpose and characteristics
The butterfly valve is processed into a sealing ring with the same material as the valve body and rotates electrically or pneumatically. The applicable temperature depends on the selected material of the valve body, and the nominal pressure is ≤ 0.6MPa. It is generally suitable for ventilation and medium flow regulation in industrial, metallurgical, environmental protection and other pipelines.
Its main features are
1. Novel and reasonable design, unique structure, light weight and rapid opening and closing.
2. Small torque, convenient operation, labor-saving and dexterous.
3. Adopt suitable materials to meet different medium temperatures and corrosive media of low, medium and high temperature.
