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, 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 disc is precisely designed, accurately machined, and guided to achieve efficient automatic shut-off at zero pressure. This design features a compact structure and low-emission service, making it ideal for various applications. 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 dynamically to flow conditions.
While swing check valves are best suited for horizontal pipeline installations, heavier disc weights can lead to chattering issues. To mitigate this, dampers or counterweights may be necessary.

Product Features

» Prevent Backflow: The cast steel swing check valve is designed to prevent reverse flow in the pipeline, ensuring unidirectional flow.
» Minimal Pressure Drop: The flow path through the valve is straight, resulting in minimal pressure drop as the media passes through.
» Automatic Operation: The disc swings open with the flow of the media and is held closed by back pressure, ensuring reliable operation.
» Versatile Installation: Cast steel swing check valves can be installed in both horizontal and vertical pipelines. However, they must be installed in the correct orientation relative to the media flow, as indicated by the flow direction arrow on the valve body.
» Customizable Accessories: A range of accessories, including bypasses, locking devices, counterweights, and more, are available to meet specific customer requirements.
