Overview of Ball Valves
Unlocking the Functionality and Components
Ball valves are essential components in fluid control systems, offering a straightforward yet effective method of regulating flow. At the core of a ball valve lies a spherical disc with a hole, known as the port, that pivots to control the flow of fluid.
When the valve is open, the port aligns with the pipeline, allowing for unrestricted flow. Conversely, closing the valve involves rotating the ball 90 degrees to block off flow completely.
This mechanism provides quick shut-off capabilities ideal for applications where rapid response is crucial. The main components of a typical ball valve include the body, ball (or sphere), seats, stem, and actuator.
The body serves as the outer casing that houses all internal components while providing connection points for piping systems. The ball is responsible for controlling flow by either obstructing or permitting passage through its central port.
Seats are sealing elements located around the port to ensure leak-tight closure when the valve is shut. The stem connects the actuator to the ball and facilitates movement to open or close it accordingly.
