Universal Cast Steel Check Valves are designed and manufactured to international standards such as API 6D, BS 1868, ASME B16.34, or equivalent, to minimize flow resistance and pressure drop. These valves are suitable for horizontal pipeline installation only, featuring a lapped and screwed seat ring for tight shut-off and long-lasting service. The precisely designed and machined disc ensures efficient automatic shut-off at zero pressure, with a compact structure and low-emission service. The standard configuration includes a bolted cover and a free-swinging clapper that responds to flow conditions. For heavier discs, dampers or counterweights are recommended to prevent chattering issues.
