Main functions and technical parameters of the product
MeiDe Valve produces High Performance Butterfly Valve deliver bi-directional zero leakage for demanding oil & gas and marine applications. Key advantages:
- Multi-Material Seats: PTFE/RTFE/UHMWPE options for -40°C~200°C, sealing at 0~100% pressure (vacuum to 300LB).
- Corrosion Resistance: Carbon steel/316SS/duplex SS bodies (NACE MR0175) for Hâ‚‚S/chloride environments.
Safety & Durability:
- Blowout-resistant 17-4PH shaft (2x ANSI torque).
- Tangential disc pins (compression-loaded, no shear failure).
- Rocker gland bridge (90% fewer packing leaks).
- Fire-Safe Design: API 607 compliant for hydrocarbon fires (30min@800°C).
Efficient Installation:
- Integrally cast mounting pad (ISO 5211 actuator compatibility).
- Extended neck for 50mm insulation (cryogenic/LNG ready).
- Applications: Firewater, cargo handling, bilge/ballast systems, and high-pressure utilities (DN50–DN1000).
