6 Installation at Site
6.1 General information/Safety regulations
The consultant, construction company or operator are responsible for positioning
and installing the valves. Planning errors and installation errors may impair the
reliable function of the valves and pose a substantial safety hazard.
NOTE
For greater ease of handling, magnets are fitted in the transducers of the sensor
equipment. Direct contact with storage media or other electrical devices sensitive to
magnetic fields should be avoided.
6.2 Installation
CAUTION
Welding in close proximity to soft-seated valves
Damage to the seat/disc interface!
▷
Ensure that the valve is not heated beyond the specified temperature limits.
Only use fasteners (e.g. to DIN EN 1515-4) and flange gaskets (e.g. to DIN EN 1514)
made of materials approved for the respective valve size. Always use all flange bolt
holes provided when connecting the valve to the piping. For details on flange
connections refer to the type series booklet and (
NOTE
Exception: DN 65 PN 16
When using steel flanges to DIN EN 1092-1 in conjunction with cast iron valves with
flanges machined to DIN EN 1092-2, ensure that for nominal size DN 65 classed
PN 16 the mating flanges are fitted offset by 22.5°.

NOTE
For the valves to reach the documented Kv values, the flow direction must
correspond to the flow direction arrow.
NOTE
Any flange caps on the line connection ports must be removed prior to installation.
