This standard provides the minimum requirements for cast-iron slide gates, including materials, general design, manufacture, testing, inspection, and shipment. The slide gates referenced in this standard are 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. They gates may be eitherof the conventional-closure or the flush-bottom-closure type and may open upward or downward.
