AWWA C516-10 Large-Diameter Rubber-Seated Butterfly Valves, Sizes 78 In. (2,000 mm) and Larger (PDF)

This standard establishes minimum requirements for rubber-seated butterfly valve assemblies, 78 in. (2,000 mm) diameter and larger with flanged ends for freshwater having a pH range of 6-12 and a temperature range of 33°F to 125°F (0.6°C to 52°C) and suitable for a maximum steady-state fluid working pressure of 150 psi (1,034 kPa [gauge]), a maximum steady-state differential pressure of 150 psi (1,034 kPa), and a maximum fully open fluid velocity of 16 ft/sec (4.9 m/sec) based on nominal valve size.
