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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 153, Valves, Subcommittee SC 1, Design,
manufacture, marking and testing.
This second edition cancels and replaces the first edition (ISO 17292:2004), which has been technically
revised with the following changes:
— scope increased to include DN 600, NPS 24, PN 63, and PN 100;
— Clause 2 “Normative references” was updated;
— Class 800 no longer restricted to reduce bore only;
— inclusion of reference and purchaser option to request valves conforming to ISO 15156 or NACE MR0103;
— expanded seat materials to include modified PTFE and reinforced modified PTFE;
— in Table 1, inclusion of higher pressure temperature ratings that are more closely aligned with
BS 5351 and account for improved performance attained from modified PTFE; separate listing for
trunnion valves has been removed from Table 1;
— revised selected bore diameters in Table 2;
— purchaser needs to specify long or short pattern face-to-face dimension on ASME flanged valves;
— clarification that the strength of the stem above the packing shall be stronger than the internal
portion at the maximum rated temperature;
— addition of purchaser option for requesting valve locking device;
— reduction of the permissible radial gap on end face flange interruptions to 0,8 mm;
— added provision for purchaser to request manufacturer to provide method for preventing excessive
pressure when fluid is trapped in centre cavity between seats;

— expanded required information on identification tag to include separate trim and seat/seal
materials. In addition, material for identification plate limited to stainless steel or nickel alloys;
— added requirement that thread sealant used on plugs for tapped auxiliary connections be capable of
the fully pressure-temperature rating of the valve;
— added purchaser option to request export packaging;
— added purchaser option to request manufacturer identify recommended spare parts.

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.
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.
