🌐 EN / DIN Standard Compliance & Testing

Our DIN series cast steel check valves are manufactured strictly according to EN 14341 specifications. Every PN25 valve undergoes rigorous hydrostatic testing to EN 12266-1 standards (shell test at 37.5 bar, seat test at 27.5 bar). Full EN 10204 3.1 Material Test Reports (MTRs) are provided to ensure complete traceability for European and international EPC projects.

🛡️ Anti-Slam Solutions for PN25 Pipelines

To safeguard district heating, municipal water, and industrial pump systems from destructive water hammer during flow reversal, BSO Ballseal provides custom anti-slam engineering:

  • Lever & Counterweight: External mechanisms designed to control the closing speed of the disc and assist in positive shut-off.
  • Resilient Seating: Optional EPDM or NBR seat rings for bubble-tight sealing in low-pressure water applications.
