Manually Operated Metallic Gas Valves for Use in Aboveground Piping Systems
|Publication Date:||8 November 1995|
This Standard applies to new valve construction and covers quarter turn manually operated metallic valves in sizes NPS l/2-2 which are intended for indoor installation as gas shutoff valves when installed in indoor gas piping between a gas meter outlet and 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 2 psig.
This Standard sets requirements, including qualification requirements, for metallic gas valves for use in an indoor gas piping system. Details of design, materials, and testing in addition to those stated in this Standard that are necessary to meet the qualification and production testing requirements of this standard remain the responsibility of the manufacturer. A valve used under a code jurisdiction or governmental regulation is subject to any limitation of such code or regulations.
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 221.15.
