The Welded Globe Valve is a globe valve connected to the pipeline system through welding. This connection method forms a tight, integral unit between the valve and the pipeline, providing excellent sealing performance and structural integrity, especially suitable for high-temperature, high-pressure, and extremely leak-sensitive applications. The disc, as the closing element, moves along the centerline of the valve seat, controlling the medium flow by varying the gap between the disc and the seat. Due to its robustness, durability, and reliable sealing characteristics, welded globe valves are widely used in industries such as thermal power plants, nuclear power plants, petrochemicals, and pharmaceuticals, where valve connection safety and reliability are paramount.
