Clean the inner cavity and sealing cover of the valve before installation. This butterfly valve can be installed on the horizontal, vertical and any Angle pipe, and can be used in both directions. The butterfly valve must be in the closed position during installation to ensure that the disc does not collide with the pipe flange. Make sure the flange welding is correct. After the butterfly valve is installed, it is not allowed to weld the flange again, so as not to burn the rubber parts and the anti-corrosion coating.
