scope:

This standard describes vertically mounted, fabricated, composite, resilientseated slide gates with full-aperture closure, designed for either seating head or unseating head or both, in ordinary water supply and wastewater service. The gates are primarily used to shut off or throttle water and wastewater flow through a rectangular or round orifice, end of channel, or in-channel opening. They may be of either conventional-closure or flush-bottom-closure type and may be opened either 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.

Purpose

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.
