Slide Gate Valve

Slide gate valves are mechanical devices used to restrict or shut-off the flow of a substance through a transport system such as piping. Slide gate valves use a flat plate that slides in a channel until it blocks the path of the flow. The terms slide gate and knife gate are often used interchangeably, though slide gate valves are commonly used in dry bulk handling systems to control the flow of granular substances.
