Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 15761 was prepared by Technical Committee ISO/TC 153, Valves, Subcommittee SC 1,
Design, manufacture, marking and testing.
Annexes A, B and C form a normative part of this International Standard. Annexes D and E are for information only.

ISO 15761:2002(E)
Introduction
The purpose of this International Standard is to establish basic requirements and practices for socket-welding, butt-
welding, threaded and flanged end, steel gate, globe and check valves with reduced body seat openings, whose
[1]
general construction parallels that specified by the American Petroleum Institute standard API 602 and the British
[2]
Standard BS 5352 .
[3] [4]
The form of this International Standard corresponds to ISO 6002 and ISO 10434 . However, it is not the purpose
of this International Standard to replace ISO 6002, ISO 10434 or any other International Standard not identified with
petroleum or natural gas industry applications.

INTERNATIONAL STANDARD ISO 15761:2002(E)
Steel gate, globe and check valves for sizes DN 100 and smaller, for
the petroleum and natural gas industries
1 Scope
This International Standard specifies the requirements for a series of compact steel gate, globe and check valves for
petroleum and natural gas industry applications.
It is applicable to valves of
— nominal sizes DN 8, 10, 15, 20, 25, 32, 40, 50, 65, 80 and 100,
1/4 3/8 1/2 3/4 1 1/4 1 1/2 2 1/2
— corresponding to nominal pipe sizes NPS , , , , 1, , , 2, , 3 and 4,
and to pressure designations of Class 150, Class 300, Class 600, Class 800 and Class 1500.
Class 800 is not a listed class designation, but is an intermediate class number widely used for socket welding and
threaded end compact valves.
It includes provisions for the following valve characteristics:
— outside screw with rising stems (OS&Y), in sizes 8� DN� 100 and pressure designations
150� Class� 1500 including Class 800;
— inside screw with rising stems (ISRS), in sizes 8� DN� 65 and pressure designations of Class � 800;
— socket welding or threaded ends, in sizes 8� DN� 65 and pressure designations of Class800 and
Class 1500;
— flanged or butt-welding ends, in sizes 15� DN� 100 and pressure designations of 150� Class� 1500,
excluding flanged end Class 800;
— bonnet joint construction — bolted, welded, threaded with seal weld, and union nut for nominal pressure rating
Class ;� 800
— body seat openings;
— materials, as specified;
— testing and inspection.
This International Standard is applicable to valve end flanges in accordance with ASME B16.5 and valve body ends
having tapered pipe threads to ISO 7-1 or ASME B1.20.1. It is applicable to extended body construction in sizes
15� DN� 50 and pressure designations of Class 800 and Class 1500, and to bellows and bellows assembly
construction as may be adaptable to gate or globe valves in sizes 8� DN� 50. It covers bellows stem seal type
testing requirements.
