Bonneted Slide Gates

Bonneted slide gates are vertical lift gates totally enclosed in steel frames and bodies then fully encased in concrete. They are typically located in conduit for high head applications. Bonneted gates can be electrically or hydraulically operated. However, most are hydraulically operated to avoid having to penetrate the bonnet cover with threaded stem sections.
