Sluice valves, also known as gate valves, are essential components in fluid control systems, particularly for regulating the flow of liquids. They consist of a gate or wedge mechanism that can be raised or lowered to either allow or block the flow of fluid through a pipe. Sluice valves are typically used in applications where a tight shut-off is required, such as in water supply networks, irrigation systems, firefighting installations, and industrial processes.
