Main functions and technical parameters of the product
MeiDe Valve produces Slab Gate Valve through-conduit slab gate valve ensures zero leakage (≤2ppm per ISO 5208) with hybrid sealing: soft EPDM insert + 3mm cemented carbide overlay. Key benefits:
- API 607 Fire-Safe: Metal-to-metal seal activates post-1400°F fire, maintaining ANSI Class VI integrity.
- Abrasion Resistance: Tungsten carbide-clad surfaces withstand 50% solids slurry (ASTM G65 verified).
- Double Piston Design: 40% lower torque vs standard valves (API 6D compliant).
- Auto Cavity Relief: Self-venting at 1.33x MAWP prevents overpressure (ASME B16.34).
- NACE MR0175 Compliance: Resists Hâ‚‚S corrosion in sour gas pipelines. Ideal for oil sands, mining, and high-temperature refineries.
