Historical (view previous versions of standard)
This specification covers the design, construction, testing, and operating requirements for hand operated, quick-change cartridge trim, in-line body and angle-body, globe-style valves for use in gas (except oxygen gas) and hydraulic systems. These valves may be used for on-off, and/or throttling applications. Valves under this specification shall be Type I or Type II; Style I or Style II; and shall have the specified size, pressure rating, and end connections. Valves furnished under this specification shall be soft-seated, globe-style valves using a cartridge in which all working parts including the seat are removable as an assembly. The pressure containing envelope shall be made of corrosion-resistant steel, nickel-copper, nickel-aluminum-bronze, or bronze. Internal parts in contact with the line media shall be made of corrosion-resistant steel, nickel-copper, copper-nickel, bronze, nickel-aluminum bronze, or naval brass. Valve construction requirements for the following are detailed: (1) soft-seating insert, (2) pressure envelope, (3) threads, (4) accessibility, (5) nonmetallic element interchangeability, (6) maintainability, (7) reversibility, (8) adjustments, (9) bidirectional operation and bubbletight shut off, (10) guiding, (11) valve operating force, (12) pressurizing rate, (13) operation, and (14) envelope dimensions. Valves shall meet the performance requirements of flow capacity, seat tightness, and external leakage. Each valve shall pass the following tests: visual examination, hydrostatic shell test, seat tightness test, and external leakage test. The envelope dimensions for angle body and inline body construction are illustrated.
