Bolted Cover Swing Check Valve, API 6D, WCB, 24 Inch, CL900

The Bolted Cover Swing Check Valve Plant specializes in manufacturing high-performance valves that meet API 6D standards. These valves are crafted from ASTM A216 WCB cast carbon steel, ensuring robustness and durability. With a large diameter of 24 inches (DN600) and rated for Class 900 LB and PN150 pressure classes, they are designed to handle high-pressure applications. The valves feature a bolted bonnet design for enhanced stability and RTJ flanged ends for secure and leak-free connections.

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 to the greatest extent possible. They are specifically designed for horizontal installation only. The lapped and screwed seat ring ensures a tight seal and long-lasting service. The valve's disc is precisely designed and machined to provide efficient automatic shut-off at zero pressure, featuring 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 acts as the closing member and responds to the prevailing flow conditions. While swing check valves are ideally suited for horizontal pipeline installations, heavier discs may cause chattering issues. In such cases, dampers or counterweights should be provided to mitigate these problems.

Product Features

» Flow Control and Prevention of Backflow: The cast steel swing check valve is specifically designed to prevent backflow in the pipeline. The flow of the media through the valve is in a straight line, which results in minimal pressure drop. As the media flows through the line, the disc swings into the open position, allowing smooth passage. When back pressure occurs in the line, it holds the disc in the closed position, effectively preventing reverse flow.
» Versatile 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. The flow direction arrow marked on the valve body indicates the proper installation direction, ensuring optimal performance and functionality.
» Customizable Accessories: To meet diverse customer requirements, a range of accessories is available. These include bypasses, locking devices, counterweights, and many others. These accessories can be added to enhance the functionality and adaptability of the valve to specific application needs.
