• For flanges with PTFE cladding: Observe the instructions for mounting cladded flanges
• The PTFE flange cladding normally acts simultaneously as a seal between the nozzle
and the device flange
• Please contact the manufacturer's support service for applications with nozzles that are
higher than indicated in the table.
Mounting cladded flanges
Note the following for cladded flanges:
• Use the same number of flange screws as the number of flange bores provided.
• Tighten the screws with the necessary torque (see Table).
• Retighten after 24 hours or after the first temperature cycle.
• Depending on the process pressure and temperature, check and retighten the screws,
where necessary, at regular intervals.
The PTFE flange cladding normally acts simultaneously as a seal between the nozzle and
the device flange.
