The ball valve is recognized for its ability to provide a quick acting shutoff due to its design, which features a spherical disc (the "ball") that can rotate within the flow path. When the valve handle is turned a quarter turn, the ball either aligns with or obstructs the flow, allowing for rapid opening and closing. This makes ball valves particularly effective in applications where prompt shutoff is critical, such as in emergency situations or in systems requiring quick maintenance.

In contrast, the globe valve has a more complex flow path with an elongated body, which can make it slower to operate and not as effective for quick shutoff. The check valve is designed to allow flow in one direction and does not offer manual shutoff capabilities. The gate valve, which operates by moving a gate into or out of the flow path, can also take longer to fully open or close compared to the ball valve. Therefore, when speed and efficiency in operating a valve are paramount, the ball valve stands out as the preferred choice.
