| Nominal diameter | Sealing face height [f]* |
|---|---|
| DN 50 - DN 200 | 3,0 mm |
| DN 300 - DN 400 | 4,0 mm |
see Fig. 3/4
| Machining | Ra (µm) | Rz (µm) |
|---|---|---|
| rotated | min. 0,8 / max. 3,2 | min. 3,2 / max. 12,5 |
Comparison of the designations acc. to the old DIN standard and the new EN standard:
| DIN 2526 | EN 1092-1 |
|---|---|
| Shape E | Shape B2 |
Comparison DIN 2636 and EN 1092-1
In contrast to the DIN standard, EN-1092-1 only specifies the pipe connection dimensions of the
ISO series. All dimensions in the ISO series are identical.
The pressure level is specified in DIN 2636 [PN 64] and EN-1092-1 [PN 63].
