  1. Caractéristiques principales
  1. 3-Piece Body Construction – Inline maintenance; internal seals and ball can be replaced without removing the valve from the pipeline.
  2. Floating Ball Design – Line pressure pushes the ball against the downstream seat, ensuring bidirectional sealing.
  3. Vacuum Suitability – Passes helium leak test with extremely low leak rate, suitable for high vacuum systems.
  4. Anti-static Device – Electrical continuity between ball, stem and body (resistance ≤10Ω) prevents static build-up.
  5. Blow-out Proof Stem – Bottom‑mounted stem with blow‑out proof design for safety.
  6. Full Bore – Low flow resistance and pressure drop.
  7. Multiple Material Options – Available in carbon steel, 304/316 stainless steel, duplex stainless steel, etc., for various corrosive media.

VII. Applications

  • Petrochemical pipelines
  • Vacuum coating, semiconductor equipment
  • Laboratory high vacuum apparatus
  • Pharmaceutical & bio‑engineering
  • Food & beverage sanitary lines
  • Power & energy
