Integral metal hard seal butterfly valve, belonging to metal seated butterfly valve, is mainly used in high, middle and low pressure, high temperature and low temperature pipelines to play a role of interception and adjustment. Integral metal hard seal butterfly valve is widely used in petroleum, chemical, metallurgy, power and other industries.
The main features of the metal seated butterfly valve:
- 1. It has compact structure, small size, light weight, flexible opening and closing.
- 2. The metal seated butterfly valve adopts three eccentric structure, has optimized design and reliable sealing performance.
- 3. The sealing vice is made of metal materials, suitable for high and low temperature, high pressure, and corrosive environments.
- 4. During the opening and closing process, there is no friction and no jam between the sealing surface of the disc and the valve seat. The valve has a long service life.
