This standard describes vertically mounted, cast‑iron slide gates designed for either seating head or unseating head, or both, in ordinary water‑supply service. The cast‑iron slide gates have machined metal faces and machined adjustable wedging devices. The cast‑iron slide gates may be used for square, rectangular, or round openings. They may be of the conventional‑closure or the flush‑bottom‑closure type. This standard also describes manual slide gate actuator mechanisms together with standard accessories. Other actuator mechanisms, including electric or hydraulic mechanisms, are described in ANSI/AWWA C540.
The purpose of this standard is to provide the minimum requirements for cast-iron slide gates, including materials, general design, manufacture, testing, inspection, and shipment.
