Resilient-Seated Cast-Iron Eccentric Plug Valves
|Publication Date:||14 June 2009|
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.
The purpose of this standard is to provide minimum requirements for resilient-seated cast-iron eccentric plug valves, suitable for water, wastewater, and reclaimed water service, including materials, application, inspection, handling, and shipping.
