This standard describes vertically mounted,fabricated stainless-steel 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 or wastewater flow through a rectangular or round
orifice, end of channel, or in-channel opening. They may be either of conventionalclosure
or flush-bottom-closure type and may open upward or downward. This
standard also describes manual gate actuator mechanisms together with standard accessories. Power-actuated mechanisms (including electric, hydraulic, or pneumatic) are described in ANSI/AWWA C541 and ANSI/AWWA C542.
