consists of valve body, disc, seal ring, transmission mechanism and other major components. Its structure is two-dimensional
This ensures the reliability of the butterfly valve as a whole in terms of corrosion resistance, high temperature resistance and abrasion resistance.
characteristic Unique structure, small and lightweight, flexible operation, labour-saving, convenient；
2. Use of eccentric principle, so that the sealing surface approximate zero friction loss, extending the service life of the valve；
