The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal – American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal – American Water Works Association. 

SCOPE
This standard covers gray-iron, ductile-iron, and cast or weld fabricated-steel or stainless steel flanged-end, low-leakage trunnion-mounted, full-port, two(2)- and four(4)-seated rotary cone valves for pressures up to 300 psi (2,100 kPa) in sizes from 6-in. through 60-in. (150-mm through 1,500-mm) diameter for use in water, wastewater, and reclaimed water systems having water with a pH greater than 6 and less than 12 and with temperatures greater than 32°F (0°C) and less than 125°F (52°C).
