Flexible Split Wedge Gate Valves - Equiwedge Main FeedWater Isolation Valve
Compliant with ASME Section III and RCC-M design codes, this valve is the industry standard for fast-acting, reliable isolation of main steam or main feedwater lines.Features
- Installed base-proven design with over 600 Equiwedge gate valves, MSIVs, and MFIVs installed in operating nuclear power generation plants.
- Minimized closing time that is 100% verifiable prior to plant startup or during outages to ensure safe shutdown of reactor to prevent meltdown.
- Gas/hydraulic actuator design provides ability to close valve within 3 to 5 seconds of receipt of signal.
- Maximized actuator readiness designed with self-contained stored energy and critical component redundancies.
- Extended service life enabled by simplified modular design with no external hose or piping connections and a 12-year maintenance cycle.
- Environmental and functional qualifications per IEEE and ASME QME-1 requirements.
