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.
