Industrial Wafer-Type Knife Gate Valve

Project goal: To design and build an 8-inch nominal pipe size wafer-type knife gate valve. The design is scalable to sizes in the product range of 2–24 inches. Research of existing valves identified the differences between valve designs. Stress analysis testing verified that the material chosen could withstand design requirements provided by the sponsor. Although a new valve body design was created, the design used the same actuators and hand wheels used by the sponsor in an existing knife gate valve. The valve prototype was built as a two-piece model, but will be cast as a single piece if the sponsor decides to put the valve into production.
