Main functions and technical parameters of the product
MeiDe Valve produces double offset butterfly valve double eccentric design ensures zero leakage (ANSI Class VI ≤2ppm) in extreme conditions (-196°C~600°C / 2500#). Key advantages:
- Cam-Action Lift: Dual-offset disc/shaft alignment eliminates seal friction, enabling 100,000+ cycles.
- Abrasion Resistance: Tungsten carbide/Stellite 6 overlays withstand 60% solid slurries.
- API 607 Fire-Safe: Metal-to-metal seal activates post-1400°F fire exposure.
- Corrosion Defense: Super duplex SS bodies (NACE MR0175) combat Hâ‚‚S/chloride erosion.
- Self-Lubricating Bearings: Maintenance-free operation in particulate-laden flows. Ideal for oil & gas, mining, and LNG cryogenic systems.
