A flow control ball valve is a type of quarter-turn valve used to regulate the flow of fluids (liquids or gases) in a pipeline. It consists of a spherical disc (the “ball”) with a hole through its center. When the valve is in the open position, the hole aligns with the pipeline, allowing fluid to flow through. Conversely, in the closed position, the ball rotates 90 degrees, blocking the flow by positioning the solid part of the ball across the pipeline.

The key to flow control in a ball valve lies in its ability to vary the degree of openness between fully open and fully closed. This is achieved by using a lever, handle, or actuator to rotate the ball. The valve can be adjusted to any position within that range to control the flow rate precisely.

flow control ball valve are preferred for applications where quick and precise control of fluid flow is essential. They offer several advantages, including minimal pressure drop, reliability, and ease of operation. These valves find use in industries such as petrochemical, water treatment, HVAC, and more, where accurate flow control is critical for safety and efficiency.
