A flange full bore ball valve is a type of industrial valve that uses a rotating ball with a large, unobstructed bore to control fluid flow, and features flanged ends for secure bolted connections to a piping system. The full bore (or full port) design ensures that the internal diameter of the valve matches the diameter of the connected pipe, minimizing pressure drop and allowing maximum flow. These valves are ideal for applications where flow efficiency, easy maintenance, and strong sealing performance are critical—commonly used in oil and gas, chemical, water treatment, and industrial process systems.
