Triple Eccentric Flange Butterfly Valve

The triple eccentric flange butterfly valve has three eccentricities. The first
eccentric shaft deviates from the center line of the sealing surface, the
second eccentric shaft deviates from the center line of the pipeline and the
valve, and the third is the angle between the unique eccentric valve seat and
the center of the pipeline. In this way, the valve seat and the sealing ring
are completely separated during the entire switching process.
