This standard describes only iron body, nonassisted, swing-check valves, 2-in. through 24-in. (50-mm through 600-mm) NPS, with mechanical-joint or flanged ends that are installed in approximately level settings in water systems. The manufacturer should be consulted for special conditions. Check valve sizes described in this standard are 2-, 2 1/2-, 3-, 4-, 6-, 8-, 10-, 12-, 14-, 16-, 18-, 20-, and 24-in.

Major revisions made to the standard in this edition include the following: the pressure ratings were revised in Sec. 1.1.4; standard end-to-end dimensions were moved from the appendix to the body of the standard in Sec. 4.4.2 and Table 2; new ductile-iron flange thicknesses were added to Sec. 4.4.7.1 and Table 3; and, a new appendix titled "Installation, Operation, and Maintenance of Swing- Check Valves for Waterworks Service" was added.
