The trunnion ball valve is an essential device for regulating the flow of fluids- steam, gas, or oil in pipeline. It is quarter-turn designs with a ball capable of rotating 90 degrees on its axis to either block or allow the flow of fluid. These valves have a spherical disk design at the center, which rotates to regulate the start-stop flow cycle. The disk often called the ball comes designed ...
