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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 17292 was prepared by Technical Committee ISO/TC 153, Valves, Subcommittee SC 1, Design,
manufacture, marking and testing in collaboration with Technical Committee ISO/TC 67, Materials, equipment
and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 6,

Introduction
The purpose of this International Standard is the establishment, in ISO format, of basic requirements and
practices for flanged, butt-welding, socket welding, and threaded end steel ball valves having flow
passageways identified as full bore, reduced bore, and double reduced bore seat openings suitable for
petroleum, petrochemical and allied industries applications that parallel those given in American Petroleum
Institute Standard API 608.
It is not the purpose of this International Standard to replace ISO 7121 or any other International Standard that
is not identified with petroleum refinery, petrochemical or natural gas industry applications.
In this International Standard, flanged end Class-designated valves have flanges in accordance with
ASME B16.5. Flanged end PN-designated valves have flanges in accordance with EN 1092-1. Valves with
ends threaded may have threads to either ISO 7-1 or ASME B1.20.1.

For the purposes of this document, the definitions for pressure designation, Class, and nominal valve size
NPS given in ASME B16.34, the definition of pressure designation PN given in EN 1333, and the following
terms and definitions apply.
3.1
DN
alphanumeric designation of size for components of a pipework system, which is used for reference purposes,
comprising the letters DN followed by a dimensionless whole number which is indirectly related to the physical
size, in millimetres, of the bore or outside diameter of the end connections
[ISO 6708:1995, definition 2.1]
3.2
anti-static design
design that provides for electrical continuity between the body, ball and stem of the valve
4 Pressure/temperature ratings
4.1 Valve rating
The service pressure/temperature rating applicable to valves specified in this International Standard shall be
the lesser of the shell rating (see 4.2) or the seat rating (see 4.3).
4.2 Shell rating
4.2.1 The pressure/temperature ratings applicable to the valve pressure containing shell (the pressure
boundary elements — e.g. body, body cap, trunnion cap, cover, body inserts) shall be in accordance with
those specified in the pressure/temperature tables of either ASME B16.34, Standard Class for Class-
designated valves, or EN 1092-1 for PN-designated valves.
4.2.2 The temperature for a corresponding shell pressure rating is the maximum temperature that is
permitted for the pressure containing shell of the valve. In general, this maximum temperature is that of the
contained fluid. The use of a pressure rating corresponding to a temperature other than that of the contained
fluid is the responsibility of the user. For temperatures below the lowest temperature listed in the
pressure/temperature tables (see 4.2.1), the service pressure shall be no greater than the pressure for the
lowest listed temperature. Consideration should be given to the loss of ductility and impact strength of many
materials at low temperature.

4.3 Seat and seal rating
4.3.1 Non-metallic elements, e.g. seats, seals, or stem seals may impose restrictions on the applied
pressure/temperature rating. Any such restriction shall be shown on the valve identification plate in
accordance with 7.4.
4.3.2 The design shall be such that, when either polytetrafluoroethylene (PTFE) or reinforced PTFE is used
for seats, the minimum valve pressure/temperature rating shall as specified in Table 1.
4.3.3 Seat ratings for other seat materials shall be the manufacturer’s standard; however, the assigned
valve service pressure/temperature rating shall not exceed that of the valve shell.

5.1 Flow passageway
The flow passageway includes the circular seat opening in the ball and the body runs leading thereto. The
body runs are the intervening elements that link the seat opening to the end connection, e.g. to the thread
end, weld end or socket end or to the end-flange. Collectively, the flow passageway through the ball and body
runs is referred to as the flow passageway. The bore is categorized in this International Standard as full bore,
reduced bore and double reduced bore. The minimum bore for each category shall be such that a hypothetical
cylinder having a diameter in accordance with Table 2 can be passed through.

conditions, is responsible for determining if larger wall thickness is required.
5.2.2 Flanged ends
5.2.2.1 Body end flanges shall comply with the requirements of ASME B16.5 for Class-designated valves

materials are suitable for the full range of service conditions, shall be performed as required by the material
specification.
5.2.2.4 End flange facing finish shall be in accordance with ASME B16.5 for Class-designated valves or
EN 1092-1 for PN-designated valves, unless otherwise specified by the purchaser.
