Main functions and technical parameters of the product
MeiDe Valve produces Bellows Sealed Globe Valve ensures zero leakage (≤1ppm per ISO 15848 AA) with triple-layer Inconel 625/Hastelloy C276 bellows. Key benefits:
- API 6FA Fire-Safe: Maintains ANSI Class IV sealing post-1400°F fire exposure.
- Corrosion Resistance: NACE MR0175 compliant for H₂S/Cl₂ media (≤10% @ 150°C).
- High-Temperature Durability: Welded bellows withstand 450°C/842°F and 25,000kPa (ASME B16.34).
- Precision Flow Control: Parabolic disc achieves ±5% CV accuracy (ISA S75.01).
- Longevity: 10,000+ cycles with 15mm short-stroke actuation. Ideal for chemical, pharma, and high-purity systems.
