Edward EQUIWEDGE MAIN STEAM ISOLATION VALVE

Evaluate this Device

Compliant with ASME Section III and RCC-M design codes, the Edward Equiwedge flexible split wedge gate valve is the industry standard for fast-acting, reliable isolation of main steam or main feedwater lines.

  • 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
