Engineered for high-pressure backflow prevention, this 2-Inch (DN50) Class 300 Swing Check Valve is manufactured from high-quality ASTM A351 CF8 (304 Stainless Steel). Featuring a robust bolted cover and a precision-lapped disc, it ensures rapid response to flow reversal with absolute bubble-tight shut-off. Strictly conforming to API 594 and BS 1868 standards, this valve delivers exceptional corrosion resistance and mechanical strength for severe-service chemical, refining, and power generation pipelines.

🏭 Engineering Highlights:

  • Design Standard: Fully compliant with API 594, BS 1868, and ASME B16.34.
  • Body Material: ASTM A351 CF8 (Superior corrosion resistance to 304 SS standard).
  • Pressure Rating: ASME Class 300 (Suitable for high-pressure fluid networks).
  • Connection: Raised Face (RF) Flanged ends strictly to ASME B16.5.

🌐 Material Integrity & High-Pressure Testing

Our CF8 stainless steel check valves are cast from virgin materials to ensure maximum purity. Every Class 300 valve undergoes stringent hydro-testing to API 598 standards (shell test at 1.5x, seat test at 1.1x nominal pressure). Full EN 10204 3.1 Material Test Reports (MTRs) are provided, guaranteeing complete traceability for your high-pressure EPC pipelines.

🛡️ Anti-Slam Solutions for Class 300

Sudden flow reversal in Class 300 systems can generate extreme water hammer. BSO Ballseal provides custom engineered solutions to safeguard your rotary equipment:

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