Wafer Type Swing Check Valves are designed for installation between two flanges in order to prevent back siphonage of contaminated fluids. Wafer Type Swing Check Valves are most often used in industrial applications, such as water and sewage treatment, where it is necessary to prevent the backflow of fluids. Wafer Type Swing Check Valves have a disc that swings open and closed in order to allow or block the flow of fluid.
Wafer Type Swing Check Valves are available in a variety of sizes and materials, making them suitable for a wide range of applications. Wafer Type Swing Check Valves are easy to install and maintain, making them an ideal choice for industrial applications.
