Slide Gate Valve
A slide gate valve is a type of valve that is designed to efficiently control the flow of free-flowing dry bulk materials like powders, granules, or pellets. These types of valves are usually installed at the outlet of dry bulk storage bins, silos, hoppers, chutes, mechanical conveyors or other similar gravity discharge points. Slide gate valve involves a rectangular blade also called a knife that is made of thick sheet metal and slides horizontally across the valve body. It can be adjusted in any position to obtain the desired product flow rate. These valves get their name as the knife slides into the flow stream to provide closure, acting like a gate. Slide gate valves are installed in pipelines and isolating valves and shouldn’t be used as control or regulating valves.
