AWWA C522-22

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).

This standard can be referenced in documents for purchasing and receiving rotary cone valves and can be used as a guide for fabricating and assembling rotary cone valves, 6 in. through 60 in. (150 mm through 1,500 mm). The requirements set forth herein apply when this document has been referenced and then only to rotary cone valves, 6 in. through 60 in. (150 mm through 1,500 mm) for water, wastewater, and reclaimed water supply service applications.
