This standard describes vertically mounted, fabricated composite, resilient-seated slide gates designed for either seating or unseating head, or both, in ordinary water supply service. These gates are primarily used to shut off water flow through a rectangular or round orifice, end of channel, or in-channel openings. They may be of the conventional closure or the flush bottom closure type and may be opened either upward or downward. The gates shall have ultrahigh molecular weight polyethylene or resilient rubber sealing surfaces, as required to meet leakage requirements.

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 C540.

The purpose of this standard is to provide the minimum requirements for fabricated composite slide gates, including materials, general design, manufacture, testing, inspection, and shipment.

This standard can be referenced in specifications for purchasing and receiving these gates and can also be used as a guide for designing and manufacturing these gates. This standard applies only to these gates as used in water supply service.
