AWWA C563-14

This standard describes vertically-mounted, fabricated composite, resilient-seated slide gates with full aperture closure, designed for either seating or unseating head, or both, in ordinary water supply and wastewater service. The gates are primarily used to shut off or throttle water and wastewater flow through a rectangular or round orifice, end of channel, or in-channel opening. They may be either conventional closure or of flush bottom-closure type and may be opened either upward or downward. This standard also describes manual gate actuator mechanisms together with standard accessories. Power-actuating mechanisms, including electric, hydraulic, or pneumatic, are described in ANSI/AWWA C541 and ANSI/AWWA C542, of latest revision.
