Double-eccentric butterfly valve

The double-eccentric butterfly valve is a series of butterfly valve products independently designed and developed by our company. The sealing surface of the valve plate seal and the valve seat seal is a "cone-to-cone" seal. The cam effect created by the two eccentricities causes the valve plate seal to tightly contact the valve seat seal surface and undergo elastic compression deformation, generating sealing pressure to achieve a reliable seal. It has a wide range of applicable working conditions and is widely used in industries such as petroleum, chemicals, oil storage, metallurgy, and power generation.
