Elite Flow Control’s Cast Steel Check Valves are engineered to prevent backflow of fluid by automatically closing before flow reversal occurs – effectively eliminating pipeline slam and water hammer. Manufactured to the highest industry standards, these valves deliver dependable performance across both clean and demanding dirty service applications.
Featuring a robust swing-type, bolted bonnet design with a non-penetrating disc shaft that allows the valve disc to fully open, these check valves ensure minimal flow restriction and maximum efficiency. The seat surface can be hardened to significantly increase wear resistance, extending service life even in the most abrasive conditions. Available with flanged or butt weld end connections, they are suitable for both horizontal and vertical installation.
Widely trusted across petrochemical, water treatment, industrial water, and wastewater services, Elite Flow Control Cast Steel Check Valves are the reliable solution for protecting your pipeline systems and equipment.
