Welded ball valve systems minimize the risk of flange leakage and separation by incorporating a fully welded body structure that forms a continuous pressure-retaining boundary.
For large-diameter valves, our manufacturing process adopts a fully welded design to eliminate intermediate joint interfaces within the pressure envelope, enhancing structural integrity and reliability under repeated pressure cycling. Precision machining is applied to maintain concentricity between sealing components and pipeline connections, ensuring long-term alignment stability and consistent sealing performance. This design is widely used in transmission pipeline applications where system downtime is costly and dependable leak prevention is essential.
