4.1 Basic series
The basic series of FTF and CTF dimensions shall be as given in Tables 5 to 31.
In those tables, there are several series which are non-preferred, but represent history and commercial
decisions made by manufacturers utilizing only one pattern for PN and Class designated valves. Those
series are identified in the relevant tables.
4.2 Face-to-face and centre-to-face dimensions
4.2.1 General
The FTF and CTF dimensions shall be in accordance with Figures 1 to 4.
For each type of valve, the basic series to be taken into consideration are given in Tables 5 to 31.
Table 1 associates the Tables 5 to 31 of the present document with the product standards of industrial
valves. In Table 5 to Table 31, the dimensions may not be given for all values of DN. For certain
sizes/types of valves, alternative dimensions are permitted and these are specified in Table 5 to
Table 31 as appropriate. The origin of the basic series is shown in Annex A.

4.2.3 Valves with lining
For valves having a resilient lining which forms the gasket joint with the mating flanges, the FTF and CTF
dimensions shall be the distance between the extremities of the valve in the installed condition. If the
dimensions for CTF and FTF differ from the standard dimensions, they shall be given by the manufacturer.
For valves having a hard lining, the thickness of the lining on the mating surface shall be included in the
FTF and CTF dimensions given in Tables 5 to 31, unless the design of the valve precludes such an
inclusion.
If this is the case, the manufacturer shall indicate the deviation from the standardized FTF or CTF
dimensions in his documentation.
4.2.4 Raised face flanges
The raised face dimensions shall be in accordance with the applicable flange standard.
4.3 Tolerances
Tolerances on FTF and CTF dimensions are given in Table 3. Both tolerances shall be fulfilled.
End flange seating surfaces shall be parallel or perpendicular. Tolerances “c” on the parallelism or
perpendicularity as shown in Figure 6 are given in Table 4.
