Introduction to Fully Welded Ball Valve
A fully welded ball valve is a critical component in various industrial pipelines. It consists of a ball with a bore through it, which rotates to control the flow of fluid. The valve body is fully welded, eliminating potential leakage points at flanges or bolted connections. This design makes fully welded ball valves highly reliable, especially in high - pressure, high - temperature, and corrosive environments. They are widely used in oil and gas transmission, chemical processing, power generation, and other industries where safety and long - term performance are crucial.
