Valve use and characteristics
The butterfly valve is made of the same material as the valve body into a sealing ring, and is electrically or pneumatically driven. The applicable temperature depends on the material selection of 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.
The main characteristics of electric ventilation butterfly valve are:
1. Novel design, reasonable, unique structure, light weight, quick opening and closing.
2. The operating torque is small, the operation is convenient, and the effort is dexterous.
3. Use adaptable materials to meet low, medium and high temperature of different media and corrosive media.
