Full Description

This standard describes reduced-wall, resilient-seated gate valves with nonrising stems (NRS) and outside screw-and-yoke (OS to 125F (0.6 to 52C). These valves are intended for applications where fluid velocity does not exceed 16 ft/sec (4.9 m/sec) when the valve is in the fully open position. Major revisions made to the standard in this edition include the following: revised to cover 42-in. NPS and 48-in. NPS sizes; revised to include integral and nonintegral thrust collar stem designs; revised to include reduced flange thickness for flanged-end valves; revised to include socket head and metric fasteners; added additional copper alloys to Table 5; and, revised to include the use of stainless-steel components (Sec. 4.2.3.5).
