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 1500, Class 2500. 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.
