What is it?:

This document specifies the basic series of face-to-face (FTF) and centre-to-face (CTF) dimensions for two-way metal valves used in flanged pipe systems. Each basic series of face-to-face and centre-to-face dimensions may be used as required with flanges of mating dimensions conforming to ISO 7005 series.

The range of sizes and pressure designations to be covered by the updated standard is:

• DN15 to DN2000
• Class 125 to Class 2500
• PN1 to PN400.

Why Is it Important?:

The existing standard is significantly out of date. It is referenced by ISO product standards. It needs bringing up to date The work in the ISO committee will take note of the work on EN558 in CEN TC69/WG1

Supersedes: This is a revision of the existing international standard. ISO 5752:1982 will superseded when the new standard is published.
