What Is Floating Ball Valve？
A Floating Ball Valve is a type of quarter-turn valve used to control the flow of fluid in pipelines. It features a floating ball design, where the ball is not fixed in place but instead floats between two seats, one upstream and one downstream. When the valve is open, the pressure of the fluid pushes the ball towards the downstream seat, creating a tight seal and preventing leakage. When closed, the ball rotates perpendicular to the flow direction, blocking the flow of fluid. Floating Ball Valves are commonly used in various industries for their reliability, ease of maintenance, and versatility in controlling fluid flow.
Disadvantages of Floating Ball Valves
- Relies solely on downstream seating for medium loads.
- Challenges in operation under high upstream pressure.
- Seating directly bears ball’s weight, limiting pressure capacity.

The Operation Theory of Floating Ball Valve
The operation theory of the Floating Ball Valve involves a floating ball design, ensuring reliable sealing. In a ZECO Valve like Barton 316C and Barton 224C, the ball is free to move between two seats. When the valve is open, the fluid pressure pushes the ball towards the downstream seat, sealing the valve. When closed, the ball rotates perpendicular to the flow, blocking it. This design ensures tight shut-off and prevents leakage in various fluid control applications.
