The available patterns for ball valves include reduced port, full port, and venturi port. This classification is crucial for understanding the flow characteristics and pressure drops across the valve, which are significant in various applications.

Reduced port ball valves have a smaller bore than the pipe diameter, which creates a restriction in flow. This design can be beneficial in applications where reduced throughput is acceptable and cost-saving is a priority.

Full port ball valves have a bore size that matches the diameter of the pipe, allowing for unobstructed flow. This design minimizes pressure drop and turbulence, making it ideal for applications where maximum flow is necessary, such as in water supply systems.

Venturi port ball valves are designed with a specific shaped passage that can create a vacuum effect or maintain a specific flow rate under certain conditions. This type is particularly useful in applications that require a precise flow control.

Understanding these patterns is essential for selecting the appropriate ball valve for a specific application, considering factors like flow rate, pressure drop, and the nature of the fluid being transported.
