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 14723 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline transportation systems.
This second edition cancels and replaces the first edition (ISO 14723:2001), which has been technically
revised.

Introduction
This International Standard is based on ISO 14313. It has been developed to address special requirements
specific to subsea pipeline valves.
It is necessary that users of this International Standard be aware that further or differing requirements can be
required for individual applications. This International Standard is not intended to inhibit a contractor from
offering, or the company from accepting, alternative engineering solutions for the individual application. This
can be particularly applicable where there is innovative or developing technology. Where an alternative is
offered, it is the responsibility of the manufacturer to identify any variations from this International Standard
and provide details.

INTERNATIONAL STANDARD ISO 14723:2009(E)
Petroleum and natural gas industries — Pipeline transportation
systems — Subsea pipeline valves
1 Scope
This International Standard specifies requirements and gives recommendations for the design, manufacturing,
testing and documentation of ball, check, gate and plug valves for subsea application in offshore pipeline
systems meeting the requirements of ISO 13623 for the petroleum and natural gas industries.
This International Standard is not applicable to valves for pressure ratings exceeding PN 420 (Class 2500).
2 Conformance
2.1 Rounding
Except as otherwise required by this International Standard, to determine conformance with the specified
requirements, observed or calculated values shall be rounded to the nearest unit in the last right-hand place of
figures used in expressing the limiting value, in accordance with the rounding method of ISO 31-0:1992,
Annex B, Rule A.
2.2 Compliance to standard
A quality system should be applied to assist compliance with the requirements of this International Standard.
NOTE ISO/TS 29001 gives sector-specific guidance on quality management systems.
The manufacturer shall be responsible for complying with all of the applicable requirements of this
International Standard. It shall be permissible for the purchaser to make any investigation necessary in order
to be assured of compliance by the manufacturer and to reject any material that does not comply.
