This standard describes resilient-seated cast-iron eccentric plug valves, 3 in. (75mm) through 72 in. (1,800 mm) in diameter, with flanged, grooved, or mechanical-joint ends for water having a pH range from 6 to 12 and a temperature range from 33 degrees F to 125 degrees F (0.6 degrees C to 52 degrees 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.

The purpose of this standard is to provide minimum requirements for water service, including materials, application, inspection, handling, and shipping.
