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.
5.Structural Features of High Performance Double Eccentric Butterfly Valve Produced by MST
1) The High Performance Double eccentric butterfly valve produced by MST has compact structure, easy assembly and disassembly, and easy maintenance.
2) The High Performance Double eccentric butterfly valve produced by MST adopts an eccentric structure to reduce the friction of the sealing ring and prolong the service life of the valve.
3) The High Performance Double eccentric butterfly valve produced by MST is completely sealed with zero leakage. Can be used in ultra-high vacuum conditions.
4) High Performance Double eccentric butterfly valve produced by MST has high-quality materials such as valve plate sealing ring, butterfly plate, and rotating shaft, which can be applied to a variety of media and different temperatures.
