本标准描述了3英寸弹性阀座铸铁偏心旋塞阀。（75毫米）至72英寸。（1800 mm）直径，带有法兰、沟槽或机械连接端，适用于pH值在6到12之间、温度在33华氏度到125华氏度（0.6摄氏度到52摄氏度）之间的水。3英寸的最小设计压力应为175 psig（1208 kPa）。通过12英寸。（75毫米至300毫米）尺寸，14英寸压力为150磅/平方英寸（1034千帕）。通过72英寸。（350毫米至1800毫米）尺寸。 本标准旨在提供水服务的最低要求，包括材料、应用、检查、处理和运输。

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.
