Gates used for Wastewater

Standards for wastewater structures deal with physical structural components, such as supports, pipes, pumps, and gates, setting out to promote the use of interoperable and reliable parts within a larger system. While these standards focus on the physical elements that contain and guide the wastewater, rather than the wastewater itself, they nevertheless remain an important part of the standardization effort for wastewater management.

AWWA C542-2016

Standard for Electric Motor Actuators for Valves and Slide Gates

This standard describes electric motor actuators that are externally mounted on gate, ball, plug, cone, globe, and butterfly valves and on slide gates suitable for use in water, wastewater, and reclaimed water facilities. The standard defines the minimum requirements for such actuating devices, including sizing considerations, general design, materials, applications, painting and coatings, data to be furnished by manufacturer, performance testing and certification, inspection, packaging, shipping, handling, and storage. This standard is one of two standards, the other being AWWA C541-08 Hydraulic and Pneumatic Cylinder and Vane-Type Actuators for Valves and Slide Gates, that replace AWWA C540 Power-Actuating Devices for Valves and Sluice Gates.

AWWA C562-2014

Fabricated Aluminum Slide Gates

This standard describes vertically-mounted fabricated aluminum slide gates with full aperture closure, designed for either seating or unseating head, or both, in ordinary water supply and wastewater service.. 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. They may be either conventional-closure or of flush bottom-closure type and may be opened 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, of latest revision

AWWA C520-2019

Knife Gate Valves, Sizes 2 In. (50 mm) Through 96 In. (2,400 mm)

The purpose of this standard is to provide minimum requirements for stainless steel and ductile-iron body knife gate valves with resilient and metal seats, including tapping knife gate valves, for use in water, wastewater, and reclaimed water systems, including materials, design, testing, rejection, marking, and shipping.
