🌐 Material Integrity & Global Standards
Our WCB cast steel check valves are manufactured from premium-grade carbon steel to ensure maximum structural integrity in industrial pipelines and general process applications. We manufacture strictly according to EN 13709 and DIN 3356. 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 pump stations, BSO Ballseal provides custom engineered solutions for our swing check valves:
- Soft Seating: Optional EPDM or NBR inserts for absolute bubble-tight shut-off in water and low-pressure applications.
- External Dampeners: Optional lever and weight configurations for controlled, non-slam closure.
- Note: Face-to-face dimensions (L) conform to EN 558 (Basic Series 48).
