Floating Ball Valve – Comprehensive Overview A floating ball valve is a widely used quarter-turn valve that uses a free-floating ball inside the valve body to provide reliable shutoff and flow control. Unlike trunnion mounted designs, the ball is held in place only by the valve seats and is free to move slightly downstream under pressure, which helps press the ball firmly against the downstream seat to achieve a tight seal. Working Principle and Design In a floating ball valve, the ball is not fixed to the stem; instead, the stem rotates the ball to open or close the valve. When the valve is closed, process pressure pushes the ball against the downstream seat, enhancing the seal. This design is simple, cost-effective, and ideal for small to medium-sized valves where torque requirements are manageable. Typical Applications and Operating Conditions Oil & Gas Pipelines – Suitable for upstream and midstream applications with moderate pressure ratings. Chemical and Petrochemical Processing – Handling a variety of fluids including corrosive and non-corrosive media. Water Treatment and Utilities – Used in clean water and wa ...
