Main functions and technical parameters of the product
MeiDe Valve producesMetal Seated Butterfly Valve triple-eccentric design ensures bi-directional zero leakage (ISO 5208 Class VI ≤10ppm) with full-metal Stellite 6 sealing surfaces. Key benefits:
- API 607 Fire-Safe: Withstands 800°C flames, maintaining ANSI Class IV sealing post-fire.
- Extreme Condition Resilience: -196°C~650°C range with 3mm Stellite 6 laser-clad overlay for slurry/erosion resistance.
- Low-Torque Operation: 30% reduced actuation force via optimized 8° conical seat geometry.
- One-Piece ASTM WCB Body: Replaces gate/ball valves in ANSI 150-600LB systems.
- ISO 15848-1 Stem Sealing: Live-loaded packing ensures ≤50ppm emissions. Ideal for refining, cryogenic, and power generation pipelines.
