Sealing face to the mating flanges

Plane, sealing face turned, N10/N12 to DIN ISO 1302
Plane, sealing face turned, N8 to DIN ISO 1302
Plane, RF (raised faced) for versions to ASME

Tapping sockets

With connection thread G½ DIN ISO 228/1, with connection dimensions to DIN 19207 form V
With threaded connection ½-14 NPT male, for version to ASME
With Ø 12 mm pipe connection for pipe union with ferrule
With welding connection, Ø 21.3 mm

Connection size

The connection size depends on the operating pressure, the temperature of the medium (DIN 19 207 and 19 211) 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.

Tapping socket: Socket length is fixed in accordance with the pressure and nominal diameter (DIN 19 205, Part 2), dimensions in mm

- Threaded connections of tapping sockets for liquids and gases up to PN 160, for steam up to PN 100,

Versions for steam lines: See "Technical description", "Function" for position of the tapping sockets.
