Universal cast steel check valves are meticulously designed and manufactured in strict compliance with international standards such as API 6D, BS1868, ASME B16.34, or their equivalents. These valves are engineered to minimize flow resistance and pressure drop, making them ideal for horizontal installation. The lapped and screwed seat ring ensures a tight seal and long-lasting service. The valve disc is precisely designed and machined to achieve efficient automatic shut-off at zero pressure, featuring a compact structure and low-emission performance. In its standard configuration, the swing check valve includes a bolted cover and a free-swinging clapper, which acts as the closing member and responds to flow conditions. While these valves are best suited for horizontal pipelines, heavier discs may cause chattering issues. In such cases, dampers or counterweights should be installed to mitigate these problems.

Product Features

» Flow Control and Minimal Pressure Drop: The cast steel swing check valve is designed to prevent backflow in pipelines. It allows flow to pass through the valve in a straight line, resulting in minimal pressure drop. The disc swings open as the media flows through the line and closes when back pressure is present.
» Versatile Installation Options: Cast steel swing check valves can be installed in both horizontal and vertical lines. However, they must be oriented correctly according to the flow direction arrow marked on the valve body to ensure proper operation.
» Customizable Accessories: A range of accessories is available to meet specific customer requirements. These include bypasses, locking devices, counterweights, and more, enhancing the functionality and adaptability of the valve.
