Gate valves are a type of valve used to control the flow of liquids and gases in pipelines. They operate by raising or lowering a gate within the valve body, allowing for a full flow when open and a complete shut-off when closed. Typically made from materials such as cast iron, stainless steel, or brass, gate valves are designed for durability and reliability in various applications.
