ASTM A216 WCB Flanged Swing Check Valve

ASTM A216 WCB Flanged Swing Check Valves are meticulously designed and manufactured in strict accordance with International Standards such as BS 1868, ASME B16.34, or equivalent standards. 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 disc is precisely designed, accurately machined, and guided to achieve efficient automatic shut-off at zero pressure.

The valves feature a compact structure and low-emission service. In their standard configuration, swing check valves come with a bolted cover and a free-swinging clapper, which acts as the closing member responding to the prevailing flow conditions. Swing check valves are ideally suited for horizontal pipeline installations. However, for heavier disc weights, chattering issues may arise, necessitating the use of dampers or counterweights.
