AWWA C560-14

This standard describes vertically- mounted, cast-iron slide gates with full aperture closing, designed for either seating head, or unseating head, or both, in ordinary water-supply and wastewater service. The cast-iron slide gates have machined metal faces and machined adjustable wedging devices. 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. The cast-iron slide gates may be used for square, rectangular, or round openings. The gates may be either of the conventional-closure or the flush-bottom-closure type and may open upward or downward. This standard also describes manual slide 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.
