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.
