Connection size
The connection size depends on the operating pressure, the temperature of the medium (DIN 19207 and 19211) and the medium, e. g.
- For liquids and gases
- up to PN 160: Thread G½ or welding connection Ø 21.3 mm
- from PN 6 and PN 400: Welding connection Ø 21.3 mm
- > PN 400: Welding connection Ø 24 mm
- For steam
- up to PN 100: Thread G½ or welding connection Ø 21.3 mm
- > PN 100: Welding connection Ø 24 mm
See "Technical description" and "Function" for position of the tapping sockets.
