DIN 3356 Swing Check Valve, ASTM A216 WCB, DN500, PN16, BW

The DIN 3356 Swing Check Valve Manufacturer offers robust and reliable swing check valves designed to meet the DIN 3356 standard. These valves feature a carbon steel body made from ASTM A216 WCB, ensuring durability and strength in high-pressure applications. With a large 20-inch diameter (DN500) and a pressure rating of 150 LB and PN16, they are well-suited for heavy-duty industrial use. The valves have butt-welded ends for seamless integration into pipelines and a bolted bonnet for easy maintenance and inspection.

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 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, with a lapped and screwed seat ring that ensures a tight seal and long-lasting service. The valve disc is perfectly designed, accurately machined, and guided to provide efficient automatic shut-off at zero pressure. These valves feature a compact structure and low-emission service. In their standard configuration, swing check valves have a bolted cover and a free-swinging clapper, which is the closing member that 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

» Preventing Backflow: Cast steel swing check valves are designed to prevent backflow in pipelines. The flow through the valve is linear, 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 Options: 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 direction of 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.
