SUPASS Cast iron ball TYPE check valve

This is a reliable Cast Iron Ball Type Check Valve designed to prevent backflow in pipelines, ensuring unidirectional flow of fluid. Its simple yet effective design utilizes a free-moving ball (rubber-coated, usually EPDM) that seats against an internal surface to stop reverse flow. Constructed from QT450 (Ductile Iron) for the body and bonnet, it offers robust durability and is suitable for various water and wastewater applications.
