4.1 Basic series
The basic series of FTF and CTF dimensions shall be as given in Table 2.
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 Table 4 to Table 14.
NOTE 1 Table 2 gives complete series. In Table 4 to Table 14 the columns of series may be incomplete.
NOTE 2 For certain sizes/types of valves, alternative dimensions are permitted and these are specified in Table 4 to
Table 14 as appropriate.
NOTE 3 The origin of the basic series is shown in Annex A (informative).
For Class designated valves with ring joint flanges, the FTF or CTF dimensions given in Table 2 shall be in-
creased by x as defined in the Table 1.

Key

4.2.2 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 manufac-
turer.
4.2.3 For valves having a resilient or hard lining, the thickness of the lining on the mating surface shall be
included in the FTF and CTF dimensions given in Table 2, unless the design of the valve precludes such an
inclusion.
If this is the case, the manufacturer shall indicate the deviation from the standardised FTF or CTF dimensions
in his documentation.
