scope:

General This Standard covers requirements for manually operated metallic valves sizes NPS 1⁄2 through NPS 2, for outdoor installation as gas shutoff valves at the end of the gas service line and before the gas regulator and meter where the designated gauge pressure of the gas piping system does not exceed 175 psi (12.1 bar). The Standard applies to valves operated in a temperature environment between −20°F and 150°F (−29°C and 66°C).
