Zhengzhou Jinggong Valve Co., Ltd.

Metal-sealed four-eccentric butterfly valve has four-fold offset design: Offset 1-Axial eccentricity: The valve's rotation center deviates from the contact plane with the sealing surface. Offset 2-Radial eccentricity: The valve's rotation center and the pipeline center are not on the same center line. Offset 3-Angular eccentricity: The valve sealing surface center forms a certain angle with the pipeline center. Offset 4-Angular eccentricity: The meshing line on the short side of the sealing surface forms a certain angle with the flow channel center line.
