EN 16722:2015 (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 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 between 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 10226–1, 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. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
