Main functions and technical parameters of the product
MeiDe Valve producesLug Butterfly Valve lug-type design ensures secure end-of-line isolation with threaded tapped lugs for ANSI/DIN/JIS flange compatibility. Key benefits:
- Bi-Directional Zero Leakage: Double-offset eccentric sealing achieves ISO 5208 Class VI (≤50ppm) at -196°C~600°
- Quick Seat Replacement: Interchangeable EPDM/FKM seats cut maintenance time by 70% vs welded valves.
- Rugged Construction: 17-4PH stainless stem with anti-blowout groove withstands 10,000+ cycles @ 600LB.
- API 609 Fire-Safe: Secondary metal seal activates post-750°C fire exposure.
- ISO 15848-1 Compliance: Live-loaded graphite packing ensures ≤50ppm fugitive emissions. Ideal for chemical plants, HVAC, and water treatment pipelines.
