EN 12982:2009 (E) 4 Introduction The basic series given in this European Standard are taken from the original series shown in Annex A. Changes made to the original series will not be automatically incorporated into this European Standard. The progress in work in the standardization of the different products may require a revision of this European Standard by adding or subtracting some basic series.

5 1 Scope This European Standard specifies the end-to-end and centre-to-end dimensions for steel butt-welding end valves with connecting dimensions of welding ends in compliance with EN 12627, used in PN and Class designated piping systems. The range of PN is: PN 10; PN 16; PN 25; PN 40; PN 63; PN 100; PN 160; PN 250; PN 320; PN 400. The range of Class is: Class 150, Class 300, Class 600, Class 900, Class 1 500, Class 2 500. The range of nominal size is: DN 8; DN 10; DN 15; DN 20; DN 25; DN 32; DN 40; DN 50; DN 65; DN 80; DN 100; DN 125; DN 150; DN 200; DN 250; DN 300; DN 350; DN 400; DN 450; DN 500; DN 600; DN 700; DN 750; DN 800; DN 900, DN 1 000; DN 1 200. NOTE 1 DN 750 is not applicable to PN designated valves. NOTE 2 See Annex B for the relationship between nominal size (DN) and nominal pipe size (NPS). NOTE 3 Valves having welding end profiles different from those specified in EN 12627, may use the same dimensions than those specified in Table 1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 736-1:1995, Valves — Terminology — Part 1: Definition of types of valves EN 736-2:1997, Valves — Terminology — Part 2: Definition of components of valves 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 736-1:1995 and EN 736-2:1997 and the following apply. 3.1 end-to end dimensions (ETE) distance expressed between the ends of the body for straight pattern valves other than those with flanged ends 3.2 centre-to-end dimensions (CTE) distance expressed between one of the ends of the body and the centre of the body for angle pattern valves other than those with flanged ends

For each type of valve, the basic series to be taken into consideration shall be in accordance with Tables 3 to 12. NOTE 1 Table 1 gives complete series. In Tables 3 to 12 the columns of series may be reduced. NOTE 2 For certain sizes/types of valves, alternative dimensions are permitted and are specified in Tables 3 to 12. NOTE 3 Basic series numbers are corresponding to the basic series given in EN 558. 4.2 Tolerances Tolerances on ETE and CTE dimensions shall be in accordance with Table 2. SIST EN 12982:2009
