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 equivalent. These valves are engineered to minimize flow resistance and pressure drop, ensuring optimal performance. They are specifically designed for horizontal installation, with a lapped and screwed seat ring that guarantees a tight seal and long-lasting service. The valve’s disc is precisely designed and machined to achieve efficient automatic shut-off at zero pressure, featuring a compact structure and low-emission service. 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 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

» Preventing Backflow: The cast steel swing check valve is designed to prevent backflow in the pipeline. It allows the media to flow in a straight line through the valve, resulting in minimal pressure drop. As the media flows through the line, the disc swings into the open position. When back pressure occurs in the line, it holds the disc in the closed position to prevent reverse flow.
» Flexible Installation Options: Cast steel swing check valves can be installed in both horizontal and vertical pipelines. However, it is crucial to install them in the correct orientation relative to 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, allowing for tailored solutions to enhance functionality and performance.
