Main Features: For the structure of the triple-eccentricity seal butterfly valve, when the valve is under the complete open state, its butterfly plate sealing face will break away from the valve seat sealing face completely; when it is opened from 0 to 90°, the butterfly plate sealing face will...
GG50 Butterfly Valve

Main features
The valve is equipped with eccentric tilting tapered valve seat sealing ring for the purpose if pressing out the sealing surface has small frictional resistance. When shutting off, it cleses more and more, so this makes sealing performance reliable, Opening can ensure that the sealing.
The special geometric structure makes the butterfly valve free of defect that other butterfly balves are unable to be sealed will due to excessively opening, so as to gurantee good sealing of the surface.
The double eccentric butterfly valve structure can gurantee that the valve fundtions mormally under high prssure and overcome the shortcomings that other valve easily leak due to sest deformation when they work under high pressure.
