FEATURES & BENEFITS
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 the reactor to prevent a meltdown
Gas/hydraulic actuator design provides the ability to close the valve within 3 to 5 seconds of receipt of a 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
