This standard establishes minimum requirements for high-performance butterfly valves, 3 in. (75 mm) through 60 in. (1,500 mm) in diameter, with various body and end types, for raw, potable, and reclaimed water having a pH range from 6 to 12 and a temperature range from 33°-125°F (0.6°-51.6°C). This standard covers three pressure ratings for high-performance butterfly valves suitable for maximum steady-state fluid working and differential pressures of 150 psig (1,034 kPa), 275 psig (1,896 kPa), and 500 psig (3,447 kPa), and maximum pipeline fluid velocity ranges of 16 ft/s (4.9 m/s), 24 ft/s (7.3 m/s), and 35 ft/s (10.7 m/s). The scope of carbon steel and stainless-steel valves includes all sizes, classes, and body styles. The scope of ductile-iron valves includes all sizes in wafer and lugged-wafer bodies. The flanged ductile-iron body scope includes 3 in. (75 mm) through 60 in. (1,500) for classes 150B, 150C, and 150D; 3 in. (75 mm) through 48 in. (1,200) for classes 275B, 275C, and 275D; and 3 in. (75 mm) through 24 in. (600 mm) for classes 500B, 500C, and 500D. This standard can be referenced in purchase documents for ductile-iron, steel, and alloy high-performance butterfly valves, which are described by the scope as defined previously.
