ASME B16.34 Swing Check Valve, ASTM A216 WCB, 6 Inch, 150 LB

This DN150 Class 150 swing check valve adopts an ASTM A216 WCB cast steel housing paired with 8# trim and raised-face flange connections. Its swing construction relies entirely on fluid movement to open during forward flow and seal shut to block reverse fluid in pipework. Built following ASME B16.34 and ASME B16.5 codes, every unit completes full visual and hydraulic tests complying with API 598 requirements. It delivers reliable unidirectional flow protection for water, hydrocarbon, and common industrial process piping across multiple industrial sectors.
