17、:2015 (E) 5 1 Scope This European Standard specifies the end-to-end and centre-to-end dimensions for valves with threaded ends with connecting dimensions in compliance with EN ISO 228-1 or EN 10226-1, used in PN and Class designated piping systems. The range of PN is: PN 10; PN 16; PN 25; PN 40; PN
18、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 4; DN 6; DN 8; DN 10; DN 15; DN 20; DN 25; DN 32; DN 40; DN 50; DN 65; DN 80; DN 100. NOTE 1 See Annex C for the relationship betw
19、een nominal size (DN) and nominal pipe size (NPS). NOTE 2 Valves having screwed end profiles different from those specified in EN ISO 228-1 or EN 102261, may use the same dimensions than those specified in Table 1. 2 Normative references The following documents, in whole or in part, are normatively
