This document specifies the requirements for a series of compact steel gate, globe and check valves for petroleum and natural gas industry applications.<\/p>\n
It is applicable to valves of:<\/p>\n
\u2014 nominal sizes DN 8, 10, 15, 20, 25, 32, 40, 50, 65, 80 and 100,<\/p>\n
\u2014 corresponding to nominal pipe sizes NPS \u00bc, ?, \u00bd, , 1, 1\u00bc, 1\u00bd, 2, 2\u00bd, 3 and 4,<\/p>\n
\u2014 pressure designations PN 16, 25, 40, 63, 100, 250 and 400, and<\/p>\n
\u2014 pressure designations Class 150, 300, 600, 800, 1 500 and 2 500.<\/p>\n
Class 800 is not a listed class designation, but is an intermediate Class number widely used for socket welding and threaded end compact valves covered by this document. There is no equivalent PN designation.<\/p>\n
This document includes provisions for the following valve characteristics:<\/p>\n
\u2014 outside screw with rising stems (OS & Y): in sizes 8 = DN = 100;<\/p>\n
\u2014 inside screw with rising stems (ISRS): in sizes 8 = DN = 65 with a pressure designation PN = 100 or Class = 800;<\/p>\n
\u2014 socket welding or threaded ends: in sizes 8 = DN = 65;<\/p>\n
\u2014 flanged or butt-welding ends excluding flanged end Class 800;<\/p>\n
\u2014 bonnet joint construction that is bolted, welded or threaded with seal weld;<\/p>\n
\u2014 bonnet joint construction that uses a union nut with a pressure designation PN = 45 or Class = 800;<\/p>\n
\u2014 body seat openings;<\/p>\n
\u2014 materials: as specified;<\/p>\n
\u2014 testing and inspection.<\/p>\n
This document covers valve end flanges in accordance with EN 1092-1 and ASME B16.5 and valve body ends having tapered pipe threads in accordance with ISO 7-1 or ASME B1.20.1. It is applicable to extended body construction in sizes 15 = DN = 50 with pressure designations Class 800 and Class 1 500 and to bellows and bellows assembly construction adaptable to gate or globe valves in sizes 8 = DN = 50. Also covered are requirements for bellows stem seal type testing.<\/p>\n","protected":false},"excerpt":{"rendered":"
