ASME B16.44-2012 (R2017)

This Standard applies to new valve construction and covers quarter-turn manually operated metallic valves in sizes NPS 4¼ and tubing sizes 1¼ O.D. These valves are intended for indoor installation as gas shutoff valves when installed in aboveground fuel gas piping downstream of the gas meter outlet and upstream of the inlet connection to a gas appliance. The valves covered by this Standard are limited to application temperatures between 32 F and 125 F at pressures not to exceed 5 psig. This Standard does not apply to manually operated gas valves which are an integral part of a gas appliance. Manually operated gas valves intended for application to a particular appliance are covered in the American National Standard for Manually Operated Gas Valves for Appliances, Appliance Connector Valves, and Hose End Valves, ANSI Z21.15/CGA 9.1.
