The primary function of the valve disc is to control the flow of fluid. The valve disc acts as a barrier within the valve body, and its position determines whether the valve is open, closed, or partially open. When the disc is in the open position, it allows fluid to pass through the valve, whereas moving it to the closed position stops the flow entirely. In applications where regulation is necessary, the valve disc can also be positioned to permit a specified amount of flow, enabling precise control of the fluid dynamics within a system.

Understanding the role of the valve disc is crucial for effective fluid management in various engineering applications, as it directly impacts system performance, efficiency, and safety.
