The numbers in the tables all relate to the
graphs on this page. The stated pressures
are valid for screw connections G 1½ A,
1½ NPT and R 1½. Boltings DN 50 acc. to
DIN 11 851 only up to max. 25 bar. When
using flanged versions, make sure to note
their nominal pressure. All electrodes are also
suitable for applications in a vacuum (-1 bar).
For electrodes certified for Ex-Zone 0, only
PTFE and FEP are approved as insulating
materials.
