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. This ensures that the flow resistance and pressure drop are minimized to the greatest extent possible. These valves are specifically designed for horizontal installation only. The lapped and screwed seat ring guarantees a tight seal and long-lasting service. The valve disc is precisely engineered, accurately machined, and guided to ensure 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 Pressure Management: 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 into the open position as the media flows through the line, and back pressure in the line holds the disc in the closed position to prevent reverse flow. 
» Versatile 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 relative to the media flow, as indicated by the flow direction arrow marked on the valve body. 
» Customization and Accessories: A range of accessories is available to meet specific customer requirements. These include bypasses, locking devices, counterweights, and more, providing enhanced functionality and adaptability for various applications.
