scope:

This standard describes vertically mounted, fabricated composite, resilientseated slide gates (hereafter simply referred to as gates) designed for either seating head or unseating head, or both, in ordinary water supply service. The 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 (UHMW) 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.

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.
