Triple Eccentric Butterfly Valve

The triple eccentric butterfly valve features three key eccentricities: the valve stem, the valve disc, and the conical sealing surface between the disc and seat. This design enables friction-free contact during closure, significantly extending valve life. The elastic sealing ring, whether mounted on the valve seat or disc, adjusts automatically under closing force to ensure uniform pressure distribution and reliable sealing. Its slight deformation further enhances the seal's effectiveness. This valve is widely used in metallurgy, power generation, petrochemicals, water systems, and municipal pipelines for flow regulation and fluid shutoff.
