    Abstract

    This specification covers the design, construction, testing, and operating requirements for pneumatic-operated, globe-style, control valves complete with actuators for various fluid systems (steam, gas, and liquid applications). The control valves with actuators may be procured under this specification complete with all associated pneumatic instrumentation necessary for the valve to function in the system application. Valves shall be of following material grades: Grade A; Grade B; Grade C; and Grade D. Valves shall be of following pressure rating types: Type 1; Type 2; Type 3; and Type 4. The inherent flow characteristics of the valve shall be specified as quick-opening, linear-opening, equal-percentage opening, or as specified. Visual examination, hydrostatic shell test, nondestructive examination, seat leakage test, and functional test shall be performed to conform with the specified requirements.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers the design, construction, testing, and operating requirements for pneumatic-operated, globe-style, control valves complete with actuators for various fluid systems (steam, gas, and liquid applications). The control valves with actuators may be procured under this specification complete with all associated pneumatic instrumentation necessary for the valve to function in the system application; however, complete and detailed requirements for air instrumentation are beyond the scope of this specification and thus are not included here. This specification is not intended to cover quarter-turn or multi-turn stem valves.

    1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
