6.1 Commissioning
6.1.1 Installation instructions
Installation Position
The valve must be installed so that the product can run out of the outlet spigot leaving no residue.
6.1.2 General welding guidelines
Sealing elements integrated in weld components must generally be removed prior to welding. To
prevent damage, welding should be undertaken by certified personnel (EN ISO 9606-1). Use the TIG
(Tungsten Inert Gas) welding process.
CAUTION
Damage and injuries due to high temperature supply
To avoid a distortion of the components, all welding parts must be welded to stress-relieved.
Allow all components to cool before assembling.
NOTICE
Damage due to impurities
Impurities can cause damage to the seals and seals area.
Clean inside areas prior to assembly.

For valves or plants/installations that are operated in the ATEX area, sufficient bonding (grounding)
must be ensured (see valid ATEX Guidelines EG).
