3.Comparison of High Performance Double Eccentric Butterfly Valve with other Valves

1) Compared with the centerline butterfly valve, the High Performance Double eccentric butterfly valve is more resistant to high pressure, has a longer life and better stability.
2) Compared with other valves, High Performance Double eccentric butterfly valve has larger diameter and lighter material and lower cost. But because there is a butterfly plate in the middle, the flow resistance is large, so the butterfly valve larger than DN200 is generally used.

4.Working Principle of High Performance Double Eccentric Butterfly Valve Produced by MST

The double eccentric effect of the High Performance Double eccentric butterfly valve enables the butterfly plate to be quickly separated from the valve seat after the valve is opened, which greatly eliminates unnecessary excessive squeezing and scraping between the butterfly plate and the valve seat, and reduces the opening resistance and reduces It reduces wear and improves the life of the valve seat.
