Universal Cast Steel Check Valves are engineered and produced in strict compliance with International Standards such as API 6D, BS 1868, ASME B16.34, or equivalent. These valves are designed to minimize flow resistance and pressure drop to the greatest extent possible. They are specifically intended for horizontal installation only. The lapped and screwed seat ring ensures a tight seal and long-lasting service. The valve disc is meticulously designed, precisely machined, and guided to achieve efficient automatic shut-off at zero pressure. The valves feature a compact structure and low-emission service. In their standard configuration, swing check valves come with a bolted cover and a free-swinging clapper, which acts as the closing member and responds to the prevailing flow conditions. Swing check valves are ideally suited for horizontal pipeline installations. However, for heavier disc weights, chattering issues may arise, necessitating the use of dampers or counterweights.

Product Features

» Backflow Prevention: The cast steel swing check valve is designed to prevent reverse flow in the pipeline. It allows for a straight-line flow through the valve, resulting in minimal pressure drop. The disc swings open as the media flows through the line, and back pressure holds the disc in the closed position to prevent backflow.
» Flexible Installation: Cast steel swing check valves can be installed in both horizontal and vertical lines. However, they must be installed in the correct orientation relative to the media flow, as indicated by the flow direction arrow marked on the valve body.
» Customization and Accessories: A variety of accessories are available to meet specific customer requirements. These include bypasses, locking devices, counterweights, and more.
