Dual Plate Wafer Check Valve is a valve designed for industrial applications. It consists of two metal plates hinged together and sealed with a rubber gasket. The hinge is located on the top of the valve so that when fluid pressure is applied to the bottom plate, the top plate is forced open, allowing fluid to pass through.
The Dual Plate Wafer Check Valve is often used in pipelines that carry liquids or gases under high pressure. When the pipeline is shut down, the Dual Plate Wafer Check Valve prevents backflow by closing automatically. Dual Plate Wafer Check Valves are available in various sizes and materials to suit different applications.
