🌐 EN / DIN Standard Compliance & Testing
Our European series cast steel check valves are manufactured strictly according to EN 14341 specifications. Every PN10 valve undergoes rigorous hydrostatic testing to EN 12266-1 standards to ensure zero leakage in low-pressure applications. Full EN 10204 3.1 Material Test Reports (MTRs) are provided to ensure complete traceability for international municipal and utility projects.
🛡️ Utility Systems & Flow Control Options
To safeguard municipal water, cooling towers, and industrial pump systems from destructive water hammer, BSO Ballseal provides custom anti-slam engineering for our low-pressure PN10 valves:
- Resilient Seating: Optional EPDM, NBR, or Viton seat rings for absolute bubble-tight sealing in water and low-pressure media.
- Lever & Counterweight: External mechanisms designed to control the closing speed of the disc and assist in positive shut-off.
- Note: Face-to-face dimensions strictly conform to EN 558-1 Series 1. Flanges drilled to EN 1092-1 PN10.
