Main functions and technical parameters of the product
MeiDe Valve producesWafer Butterfly Valve wafer design ensures zero bi-directional leakage (ISO 5208 Class VI) with dual-offset eccentric sealing. Key advantages:
- Multi-Flange Fit: ANSI/DIN/JIS/GOST compatibility eliminates adapter needs.
- Interchangeable Seats: Replace EPDM/FKM seats in 30min, extending lifespan 5x vs welded types.
- ISO 15848-1 Stem Packing: Graphite/316SS composite guarantees ≤50ppm emissions (-196°C~600°C).
- Anti-Blowout Stem: 17-4PH steel with retention groove withstands 10,000+ cycles @ 600LB.
- Compact & Lightweight: 50% thinner profile vs lug-type valves (DN50-DN1200). API 609 fire-safe certified for HVAC, chemical, and marine pipelines.
