🌐 Material Integrity & Global Standards

Unlike standard commercial valves, our WCB cast steel check valves are manufactured from premium-grade carbon steel to ensure maximum pressure containment and superior structural integrity in heavy-duty oil, gas, and water applications. We manufacture strictly according to BS 1868, API 594, and ASME B16.34. Full EN 10204 3.1 Material Test Reports (MTRs) are provided with every shipment, guaranteeing complete traceability for your EPC projects.

🛡️ Anti-Slam & Advanced Flow Control Options

To prevent destructive water hammer caused by sudden flow reversal in large-scale pump stations, BSO Ballseal provides custom engineered solutions for our swing check valves:

  • Soft Seating: Optional PTFE or Viton inserts for absolute bubble-tight shut-off in critical fluid applications.
  • External Dampeners: Optional lever, weight, and hydraulic dashpot configurations for controlled, non-slam closure.
