Fully-welded ball valve is constructed with all-welded body to efficiently reduce leak paths to the environment, minimizing the leakage rate. The ball valve is mainly utilized in pipelines to control of fluid flow. Adapting to customer’s application needs, the fully-welded ball valve is available in buried installation type with stem extensions, enabling the valve to be suited for inaccessible areas and underground applications.
