- 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.
