| description abstract | This specification covers valves for automatically venting air from mains in steam heating systems. Valves shall be one of the following types and classes, as specified (see 6.2): Type I - Without vacuum holding device. Type II - With vacuum holding device. Class 1 - Low pressure - up to 15 pound-force per square inch gage (psig) (103.4 kilopascal (kPa)). Class 2 - Medium pressure - 16 to 65 psig (110.3 to 448.2 kPa). Class 3 - High pressure - 66 to 125 psig (445.1 kPa to 861.8 kPa). Intended Use: The air-venting valves covered by this specification are intended primarily for venting mains in one-pipe-and two-pipe gravity steam heating systems. The valves may also be used for venting unit heaters and systems supplying steam to process equipment, and steam-heated galley equipment. Type I valves are used in systems operating at or above atmospheric pressure. Type II valves are intended primarily for use in one-pipe vapor-vacuum systems. Class 3 valves are intended for special applications not associated with gravity steam-heating systems. | |
