Manually Operated Metallic Gas Valves for Use in House Piping Systems
This Standard applies to new valve construction and covers quarter turn manually operated valves in sizes NPS ¼-4 and tubing sizes ¼-1 O.D. These valves are intended for indoor installation as gas shutoff valves when installed in above ground 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 intended for service at temperatures between 32ºF (0ºC) and 125ºF (52ºC) at pressure ratings not exceed 5 psi (0.34 bar). When so designated by the manufacturer, these valves may be installed for service outdoors and/or at temperatures below 32ºF (0ºC) and/or above 125ºF (52ºC).
