Flange type fully welded ball valve 02

The flange type fully welded ball valve 02 should be installed in the correct way to lift the valve. In order to protect the stem, do not tie the lifting chain to the hand wheel, gear box or actuator. Do not remove the protective caps on both ends of the valve sleeve before welding. Welded direct-buried fully welded ball valves are connected to the main pipeline by welding.
