Understanding Flow Characteristics in Semi-Closed Ball Valves
Why does it matter if a ball valve is semi-closed in operation? In fluid-handling systems across oil & gas, petrochemicals, mining, power generation, and industrial processing, ball valves are routinely selected for their durability, shut-off performance, and ease of operation. However, when a ball valve is operated in a semi-closed (partially throttled) position, the flow characteristics change significantly—and with them, the mechanical environment experienced by downstream equipment and piping.
