Universal Cast Steel Check Valves are meticulously designed and manufactured in strict adherence to 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 to the greatest extent possible. They are specifically designed for horizontal installation, ensuring optimal performance in such orientations. The seat ring is precision-lapped and screwed in place, guaranteeing a tight seal and long-lasting service life. The valve disc is meticulously designed, accurately machined, and guided to achieve efficient automatic shut-off even at zero pressure. This design also ensures a compact structure and low-emission service. In its standard configuration, the swing check valve features a bolted cover and a free-swinging clapper, which serves as the closing member and responds dynamically to flow conditions. While swing check valves are ideally suited for horizontal pipeline installations, heavier disc weights may lead to chattering issues. To mitigate this, dampers or counterweights can be incorporated to enhance stability and performance.

Product Features

» Flow Control and Prevention of Backflow: The cast steel swing check valve is specifically designed to prevent backflow in the pipeline. It allows 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, facilitating smooth passage. When back pressure occurs, the disc is held securely the in closed position, effectively preventing reverse flow.
» Versatile Installation Options: Cast steel swing check valves offer the flexibility of being installed in both horizontal and vertical lines. However, it is crucial to install them in the correct orientation relative to the flow media, as indicated by the flow direction arrow marked on the valve body. This ensures optimal performance and prevents potential issues related to improper installation.
» Customizable with Accessories: To meet diverse customer requirements, a range of accessories is available for these valves. These include bypasses for alternative flow paths, locking devices for enhanced safety and control, counterweights to address issues related to heavy disc weights, and many other options. These accessories can be tailored to specific applications, providing additional functionality and customization to suit individual needs.
