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).

Introduction

This International Standard establishes face-to-face and centre-to-face dimensions for metal marine

valves to permit a degree of dimensional interchangeability in ships and marine piping.

It is intended for use in selecting valves in piping for ships and marine services.

This International Standard specifies face-to-face and centre-to-face dimensions of valves for ships and

marine services including supplementary series of special valves under Standards for ships, other than

those specified in ISO 5752:1982 for variety of types and series of general industrial valves.

The tables of face-to-face dimensions in this International Standard and those specified in ISO 5752:1982

represent a considerable rationalization of international practices for metallic valves to be used

worldwide in the shipbuilding and marine services. The pressure/temperature ratings for the different

types of valves are those to be specified in the valve product standards for the types of valve and

materials used.

INTERNATIONAL STANDARD ISO 17602:2014(E)
Ships and marine technology — Metal valves for use in
flanged pipe — Face-to-face and centre-to-face dimensions
1 Scope

This International Standard specifies the basic series of face-to-face or centre-to-face dimensions for

two-way metal valves used in flanged pipe systems for ship and marine services. Each series of face-to-

face or centre-to-face dimensions can be used as required with flanges of mating dimensions conforming

to ISO 7005-1, ISO 7005-2, and ISO 7005-3 or other national standards.

The range of pressure ratings, in “K” values, is 5 - 10 - 16 - 20 - 30 - 40 and those specified in ISO 5752.

The range of nominal sizes, in “DN” or “A” values, is 15 - 20 - 25 - 32 - 40 - 50 - 65 - 80 - 100 - 125 - 150 -

200 - 250 - 300 - 350 - 400 - 450 - 500 - 550 - 600 - 650 - 700 - 750 - 800 - 900 - 1 000 - 1 200.

NOTE For information, pressure ratings at room temperature (cold ratings up to 120 °C) of K-series flanges

are approximately as follows.
Pressure class 5K 10K 16K 20K 30K 40K
Pressure rating (RT) 0,7 MPa 1,4 MPa 2,2 MPa 3,4 MPa 5,1 MPa 6,8 MPa

Pressure rating can differ by valve materials, sizes, and types. Reference shall be made to relevant product

standards. For details of pressure temperature ratings of K-series flanges, refer to JIS Standards in the

bibliography of this International Standard. JIS F7300 specifies a comprehensive guide for selection of

valves listed in Tables 1 to 5.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
nominal size (DN: A)

alphanumeric designation of size for components of a pipework system, which is used for reference

purposes

Note 1 to entry: It comprises the letters DN or A 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.

---------------------- Page: 6 ----------------------
ISO 17602:2014(E)

Note 2 to entry: Designation is to be indicated by the letters DN, followed by a number, or a number followed by

the letter A.

Note 3 to entry: The number following the letters DN or A does not represent a measurable value and should not

be used for calculation purposes except where specified in the relevant standard.

3.2
nominal pressure
internal pressure that a pipe is designed to safely withstand

Note 1 to entry: Nominal pressures in this International Standard follow one of the following systems, the K rating

system to ISO 8277 and the PN rating system or the class rating system to ISO 5752

3.3
face-to-face dimension (for straight pattern valves)

distance, in millimetres, between the two planes perpendicular to the valve axis located at the extremities

of the body end ports or as can be specified in the relevant valve products standards

Note 1 to entry: The face-to-face dimension for butterfly valves is the distance between the extremities of the

valve in the installed conditions. See Figure 3 a) as an example to know how face-to-face dimension is measured.

3.4
centre-to-face dimension(for angle pattern valves)

distance, in millimetres, between the plane located at the extremity of either body end port and

perpendicular to its axis and the other body end port axis

Note 1 to entry: See Figure 3 b) as an example to know how centre-to-face dimension is measured.

Note 2 to entry: It should be taken into account that an angle pattern valve can have different centre-to-face

dimensions for its inlet port and outlet port.
4 Typical types of valves
Typical types of valves shall be as given in Figures 1 to 6.
Figures 1 to 6 are intended to be a diagrammatic only and
