BALL VALVES
A ball valve is a widely used device in fluid control systems designed for regulating the flow of liquids or gases through a pipe. It operates by using a spherical ball with a hole through its center, which rotates within the valve body to allow or block flow. Ball valves are ideal for applications requiring quick shutoff or reliable isolation of flow. Ball valves provide excellent sealing capabilities and are particularly effective in situations where tight shutoff is essential.
Ball valves are a crucial component in many systems due to their reliability and efficiency, serving as an optimal solution for controlling flow in pipelines. Commonly found in industries such as water supply, oil and gas, chemical processes, and power generation, ball valves are essential for managing both small and large volumes of fluid securely.
