scope:

This standard describes resilient-seated cast-iron eccentric plug valves, 3 in. (75 mm) through 72 in. (1,800 mm) in diameter, with flanged, grooved, or mechanical- joint ends, for water, wastewater, and reclaimed water systems having a pH range from 6 to 12 and a temperature range from 33°F to 125°F (0.6°C to 52°C). The minimum design pressure shall be 175 psig (1,208 kPa) for 3-in. through 12-in. (75-mm through 300-mm) sizes and 150 psig (1,034 kPa) for 14-in. through 72-in. (350-mm through 1,800-mm) sizes and a maximum full-open fluid velocity of 8 ft/sec (2.4 m/sec) based on nominal valve size.

Definition of classification. 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.

"A" designation. The designation "A" defines the flow-rate capabilities with the valve in the fully open position. Valves designated "A" are rated for a maximum velocity of 8 ft/sec (2.4 m/sec) in the piping section upstream of the valve.

Purpose

The purpose of this standard is to provide minimum requirements for resilientseated cast-iron eccentric plug valves, suitable for water, wastewater, and reclaimed water service, including materials, application, inspection, handling, and shipping.
