C504-06: AWWA Standard for Rubber-Seated Butterfly Valves (PDF)

This standard establishes minimum requirements for rubber-seated butterfly valves, 3 in. (75 mm) through 72 in. (1,800 mm) in diameter, with various body and end types, for freshwater having a pH range from 6-12 and a temperature range from 33° to 125°F (0.6° to 52°C). This standard covers rubber-seated butterfly valves suitable for a maximum steady-state fluid working pressure of 250 psi (1,723 kPa, a maximum steady-state differential pressure of 250 psi (1,723 kPa), and a maximum full open velocity of 16 ft/sec (4.9 m/sec). Valves described in this standard are provided in four body types and in classes as follows: Wafer valves, Class 150B, in sizes 3-20 in. (75-500 mm); short-body and long-body flanged valves, Class 25A, class 25B, class 75A, class 75B, class 150A, and class 150B, in sizes 3-72 in. (75-1,800 mm), and class 250B in sizes 30-48 in.

In each case, the numeric designation represents the pressure rating (the maximum steady-state fluid working pressure, in pounds per square inch gauge) and also the maximum steady-state differential pressure, in pounds per square inch, for which the valve is designed. The designations A and B define the flow-rate capabilities with the valve in the fully open position. A valves are rated for a maximum velocity of 8 ft/sec (2.4 m/sec), and B valves are rated for a maximum velocity of 16 ft/sec (4.9 m/sec) in the piping section upstream of the valve.

Industry Insights

AWWA industry partners offer a wealth of knowledge, insights and solutions on crucial water-sector issues and opportunities.

Wastewater Collection Systems

Wastewater collections systems are comprised of gravity pipes, manholes, tanks, lift stations, control structures, and force mains that gather used water from residential and nonresidential customers and convey the flow to the wastewater treatment plant. It takes thousands of miles of pipeline to collect this wastewater so it can be treated and returned to the environment.
