Bolted Bonnet Swing Check Valves, BS 1868, A216 WCB, 4 Inch

The Bolted Bonnet Swing Check Valves Plant offers a robust solution for industrial fluid control. These valves are meticulously designed in accordance with the stringent BS 1868 standard, ensuring high reliability and performance. Constructed with a carbon steel ASTM A216 WCB body, they provide exceptional durability and resistance to harsh operating conditions. With a 4-inch (DN100) size and rated for Class 600 LB or PN100 pressure, these valves are suitable for demanding applications. The RF flanged ends facilitate easy installation and integration into existing piping systems.

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, 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 ensure efficient automatic shut-off at zero pressure. It features a compact structure and low-emission service, making it suitable for a wide range of 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 to the prevailing flow conditions. While swing check valves are best suited for horizontal pipeline installations, heavier disc weights can sometimes lead to chattering issues. To mitigate this, dampers or counterweights may be necessary to ensure smooth operation and prevent unwanted vibrations.

Product Features

» Backflow Prevention: Cast steel swing check valves are designed to prevent backflow in the pipeline. The flow travels 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, while 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 are available to meet specific customer requirements. These include bypasses, locking devices, counterweights, and more.
