- Hauptmerkmale
- 3‑Piece Body Construction – Easy inline maintenance without removing the valve from the pipeline.
- Floating Ball Design – Line pressure pushes the ball against the downstream seat for bidirectional sealing.
- Full Bore – Low flow resistance and pressure drop.
- Anti‑static Device – Electrical continuity ≤10Ω between ball, stem and body; prevents static build‑up.
- Blow‑out Proof Stem – Bottom‑mounted stem with blow‑out proof design for safety.
- Multiple Material Options – Carbon steel, 304/316 stainless steel, duplex, etc.
- Fire Safe Design Available – Optional API 607.
- Anwendungen
- Petrochemical pipelines
- Natural gas, compressed air systems
- Water treatment
- Pharmaceutical & bio‑engineering
- Food & beverage
- General industrial fluid control
