Designed to deliver exceptional corrosion resistance and reliable backflow prevention, this 2-Inch (DN50) Class 150 Swing Check Valve is manufactured from high-purity ASTM A351 CF8M Stainless Steel (316 SS). Unlike generic cast valves, our heavy-wall bolted bonnet design ensures zero leakage and safe operation in harsh chemical, marine, and corrosive process environments. Strictly conforming to BS 1868 and API 594 specifications, it provides rapid, automatic closure to protect your critical piping infrastructure.

🏭 Engineering Highlights:

  • Design Standard: Fully compliant with BS 1868, API 594, and ASME B16.34.
  • Body Material: ASTM A351 CF8M (Molybdenum-alloyed for superior pitting resistance).
  • Safety Function: Unrestricted flow path with non-slam automatic closure capabilities.
  • Connection: Raised Face (RF) Flanged ends strictly to ASME B16.5.

🌐 Material Integrity & Global Standards

Unlike standard commercial valves, our CF8M stainless steel check valves are cast from virgin materials to ensure maximum purity and superior pitting resistance in chemical environments. 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 critical 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 low-pressure and corrosive fluid applications.
  • External Dampeners: Optional lever, weight, and hydraulic dashpot configurations for controlled, non-slam closure.
