ویژگی‌های کلیدی

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