1. The valve is equipped with eccentric tilting tapered valve seat sealing ring for the purpose of pressing out the sealing surface has small frictional resistance. When shutting off, it closes more and more, So this makes sealing performance reliable. Opening can ensure that the sealing surface completely gets rid of contact and is not damaged.
2. The special geometric structure makes the butterfly valve free of defect that other butterfly valves are unable to be sealed well due to excessively opening, so as to guarantee good sealing of the surface.
3. The double-eccentric butterfly valve structure can guarantee that the valve functions normally under high-pressure and overcome the shortcomings that other valves easily leak due to seat deformation when they work under high pressure.
4. This valve adopts different sealing surface materials according to the requirement of media in order to guarantee that the sealing surface is of damage resistance, erosion resistance and corrosion resistance, with long-term working life.
