Status: Valid

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.
