26、 are drafted separately for PN-designated valves in EN 558-1 and for Class designated valves in EN 558-2. The basic series in this standard are taken from the origin series shown in Annex A (informative). Changes made to the origin series will not be automatically incorporated into this standard. Th
27、e numbers of the basic series are maintained as in ISO/DIS 5752:1993. 1 Scope This Part of this standard specifies face-to-face (FTF) and centre-to-face (CTF) dimensions for PN designated metal valves used in flanged pipe systems. This Part of this standard covers valves having the following PN and

31、Part 1: Definitions of types of valves. EN 26554, Flanged automatic steam traps Face-to-face dimensions. 3 Definitions For the purposes of this standard, prEN 736-1 and the following definitions apply: 3.1 face-to-face dimension (FTF) (for straight pattern valves) the distance, expressed in millimet
32、res, between the two planes perpendicular to the valve axis located at the extremities of the body end ports or as may be specified in the relevant valve product standard (see Figure 1 and Figure 2) 3.2 centre-to-face dimension (CTF) (for angle pattern valves) the distance, expressed in millimetres,
33、 between the plane located at the extremity of either body end port and perpendicular to its axis and the axis of the other body end port (see Figure 1 and Figure 2) 4 Dimensions and tolerances 4.1 Basic series The basic series of FTF and CTF dimensions shall be as given in Table 1. For each type of
34、 valve, the basic series to be taken into consideration are given in Table 3 to Table 17. 4.2 Dimensions for unlined valves For unlined valves the FTF and CTF dimensions shall be in accordance with Figure 1 and Figure 2. 4.3 Dimensions for lined valves 4.3.1 For valves having a resilient lining whic
35、h 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. The overall valve dimensions before assembly shall be provided by the manufacturer. 4.3.2 For valves having resilient or hard linings as
36、 a regular production feature the thickness of the lining on the mating surface shall be included in the FTF and CTF dimensions given in Table 1, unless the design of the valve precludes such an inclusion. Where the design does not permit the lining to be included in the FTF and CTF dimensions given
37、 in Table 1, then the thickness of the lining may be added to the basic dimension. 4.3.3 For valves having resilient or hard linings which are not normally a regular production feature, the thickness of the lining on the flange faces may be added to the FTF and CTF dimensions given inTable 1.
