Abstract:

This specification covers the design, construction, testing, and operating requirements for self-contained pressure-reducing valves for air or nitrogen systems. Pressure-reducing valves shall be either: type I - inlet outlet end connections of the same pressure rating or type II - outlet end connection pressure rating lower than the inlet end connection rating. Valves shall incorporate the design features specified. Pressure-reducing valves shall meet the performance requirements prescribed. Hydrostatic shell test, seal tightness test, and external leakage test shall be performed to meet the requirements prescribed.

Scope:

1.1 This specification covers the design, construction, testing, and operating requirements for self-contained pressure-reducing valves for air or nitrogen systems.

1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
