Large Metallic Valves for Gas Distribution Manually Operated, NPS 2 1/2 (DN 65) to NPS 12 (DN 300), 125 psig (8.6 bar) Maximum
N B16.38
Annotation
Valve Types
This Standard covers requirements for manually operated metallic valves in nominal sizes 21 2 (DN 65) through 12 (DN 300) having the inlet and outlet on a common centerline. These valves are intended for controlling the flow of gas from open to fully closed positions, for use in distribution and service lines where the maximum gage pressure does not exceed 125 psig (8.6 bar). Valve seats, seals, and stem packing may be nonmetallic.
Application
This Standard sets forth the minimum capabilities, characteristics, and properties that a newly manufactured metallic valve must possess in order to be considered suitable for use in piping systems indicated above, carrying natural gas, manufactured gas [includes synthetic natural gas (SNG)], and liquefied petroleum gases (distributed as a vapor, with or without the admixture of air) or mixtures thereof.

Типы клапана
Этот Стандарт закрывает требования для вручную управляемых металлических клапанов в номинальных размерах 21 2 (DN 65) до 12 (DN 300), имеющий входное отверстие и выход на общей средней линии. Эти клапаны предназначаются для управления потоком газа от открытого до полностью закрытых положений для использования в распределении и линиях обслуживания, где максимальное манометрическое давление не превышает 125 фунтов на квадратный дюйм (8.6 брусков). Седла клапана, изоляции и упаковка основы могут быть неметаллическими.
