21、given in this European Standard are taken from the original series shown in Annex B. Changes made to the original series will not be automatically incorporated into this European Standard. DIN EN 16722:2015-12 EN 16722:2015 (E) 5 1 Scope This European Standard specifies the end-to-end and centre-to-
22、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 63; PN 100; PN 160; PN 250; PN 320; PN 400. The range of Class is: Class 150, Clas
23、s 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 between nominal size (DN) and nominal pipe size (NPS). NOTE 2 Valves having screwed en
24、d 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 referenced in this document and are indispensable for its application.
