This standard covers gray-iron, ductile-iron, and cast-steel flanged-end, low-leakage, shaft- or trunnion-mounted, full-port, and double- and single-seated ball valves for pressures up to 150 psi (1,050 kPa) in sizes 6 in. through 60 in. (150 mm through 1,500 mm) diameter and pressures up to 300 psi (2,100 kPa) in sizes from 6 in. through 48 in. (150 mm through 1,200 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 32ºF (0ºC) and less than 125ºF (52ºC). The major changes made in this revision of the standard are too numerous to list here and can be found in the foreword section of the standard.
