Universal Cast Steel Check Valves are meticulously designed and manufactured in strict compliance with International Standards such as API 6D, BS 1868, ASME B16.34, or their equivalents. These valves are engineered to minimize flow resistance and pressure drop to the greatest extent possible. They are specifically designed for horizontal installation, with a lapped and screwed seat ring that ensures a tight seal and long-lasting performance. The valve disc is precisely designed, accurately machined, and guided to achieve efficient automatic shut-off at zero pressure. The valves feature a compact structure and low-emission service capabilities.
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. While swing check valves are ideally suited for horizontal pipeline installations, heavier disc weights may lead to chattering issues. In such cases, dampers or counterweights should be provided to mitigate these problems.

Product Features

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