Universal Cast Steel Check Valves are meticulously designed and manufactured in strict compliance with international standards such as API 6D, BS1868, and ASME B16.34. 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 responding to flow conditions. While swing check valves are best suited for horizontal pipeline installations, heavier disc weights may lead to chattering issues. In such cases, dampers or counterweights are recommended.

Product Features

» Preventing Backflow: The cast steel swing check valve is designed to prevent backflow in the pipeline. It allows 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.
» Flexible Installation: Cast steel swing check valves can be installed in either horizontal or vertical lines. However, they must be installed in the proper orientation relative to the media flow, as indicated by the flow direction arrow marked on the valve body.
» Customizable Accessories: A variety of accessories, such as bypasses, locking devices, counterweights, and more, are available to meet specific customer requirements.
