IEC 60534-3-1:2019
IEC 60534-3-1:2019 specifies face-to-face (FTF) and centre-to-face (CTF) dimensions for given nominal sizes and pressure ratings of flanged, two-way, globe-type, straight pattern and angle pattern control valves This second edition cancels and replaces the first edition published in 2000. This edition constitutes a technical revision.
 This edition includes the following significant technical changes with respect to the previous edition:
 a) This standard has been extended to cover face-to-face dimensions and centre-to-face dimensions for control valves PN 160 and PN 250 (Class 900 and 1500)
 b) Definitions of end-to-end dimensions and centre-to-end dimensions have been added for valves with flange facings where the gasket contact surfaces are not located at the extreme ends of the valve
 c) Table 5 of adjustment value "X" for end-to-end dimensions of straight pattern valves with ring joint ends has been added
 d) ANSI/ISA references have been added in Tables 1 to 4
 e) ANSI/ISA references have been added in the bibliography
