Main functions and technical parameters of the product
MeiDe Valve producesTriple Offset Butterfly Valve triple offset design ensures metal-to-metal sealing with zero leakage (ISO 15848-1 certified). The 3-eccentric structure eliminates friction, enabling 50,000+ cycles at 600LB. Key advantages:
- Bi-Directional Sealing: Full Class VI shutoff in both flow directions.
- Quick-Change Seat System: Replace seals in 15min without disassembly, reducing downtime by 65%
- Space-Saving: 40% lighter/smaller vs gate valves (ASME 150-600LB).
- Fire-Safe API 609 Compliance: 750°C-rated secondary seal activates post-fire.
- Live-Loaded Packing: Graphite/stainless composite ensures ≤50ppm emissions (-196°C~550°C).
- Integrates 17-4PH anti-blowout stem and conical disc alignment for petrochemical/power plant critical isolation.
