This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2017, and conflicting natio

Basic series

The basic series of FTF and CTF dimensions shall be as given in Table 2.

Face-to-face and centre-to-face dimensions

General

The FTF and CTF dimensions shall be in accordance with Figures 1 to 4 and Table 2

For each type of valve, the basic series to be taken into consideration are given in Table 5 to Table 16

NOTE 1 Table 2 gives complete series In Table 5 to Table 16, 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 5 to Table 16 as appropriate

NOTE 3 The origin of the basic series is shown in Annex A (informative).

Class designated valves with ring joint flanges

For Class designated valves featuring ring joint flanges, the FTF and CTF dimensions specified in Table 2 must be adjusted by an additional value, \( x \), as outlined in Table 1 and illustrated in Figure 5 Specifically, the FTF dimension is calculated as the value from Table 2 plus \( x \), while the CTF dimension is determined by adding 0.5 times \( x \) to the value from Table 2.

Valves with lining

For valves with a resilient lining that creates the gasket joint with mating flanges, the Face-to-Face (FTF) and Center-to-Center (CTF) dimensions refer to the distance between the valve's extremities when installed If the FTF and CTF dimensions deviate from standard specifications, the manufacturer must provide the correct measurements.

For valves with a resilient or hard lining, the thickness of the lining on the mating surface must be considered in the FTF and CTF dimensions specified in Table 2, unless the valve's design prevents this inclusion.

The basic series of FTF and CTF dimensions shall be as given in Table 2

If this is the case, the manufacturer shall indicate the deviation from the standardized FTF or CTF dimensions in his documentation.

Raised face flanges

The raised face dimensions shall be in accordance with the applicable flange standard.

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

Table 9 — Globe valves — Straight and oblique pattern PN / ClassFTF series 1 2 5 7d101418d

The article outlines various pressure ratings and classes for valves, including PN 6 to PN 400 and Class 125 to Class 2500 Specific recommendations are provided for steel and cast iron valves, such as using 356 for PN 10 and PN 16 Class 150 steel valves (DN 125) and 965 for cast iron valves (DN 450) Additionally, for PN 25 and PN 40 Class 300 steel valves, the article suggests using sizes 203 (DN 25), 216 (DN 32), 229 (DN 40), and 559 (DN 200) It is important to note that the series applies exclusively to copper alloy valves and should not be used for cast iron or steel valves, and the information pertains to both flanged and wafer types.

Table 11 — Check valves — Flanged typea PN / ClassFTF series 1 2 5 7b101418b

The article outlines various pressure ratings and classes for lift check valves, specifically detailing the specifications for copper alloy valves and noting that these guidelines do not apply to cast iron or steel valves For PN 16, Class 150 lift check valves in steel, the recommended models are 356 (DN 125) and 406 (DN 150) For PN 40, Class 300 lift check valves in steel, the suggested models include 203 (DN 25), 216 (DN 32), 229 (DN 40), and 559 (DN 200) Additionally, for PN 16 valves in cast iron, model 965 (DN 450) is advised, while for PN 16 swing check valves in steel, model 864 (DN 400) should be used.

Table 12 — Check valves — Wafer type

Table 13 presents the Globe control valves across various PN and Class series, including the FTF series (straight pattern) and CTF series (angle pattern) The valves are categorized by pressure ratings, with options available from PN 10 to PN 400 and Class 150 to Class 2500 Specific notes indicate that for CTF Class 900, half the dimensions of series 105 should be used, while for Class 1500 and Class 2500, half the dimensions of series 106 and series 77, respectively, are applicable.
