Installation:
2. Ensure the suitability of the valve for each respective use.
The valve must be appropriate for the piping system oper-
ating conditions (medium, medium concentration, temper-
ature and pressure) and the prevailing ambient conditions.
Check the technical data of the valve and the materials.
3. Shut off plant or plant component.
4. Secure against recommissioning.
5. Depressurize the plant or plant component.
6. Completely drain the plant (or plant component) and let it
cool down until the temperature is below the media vapor-
ization temperature and cannot cause scalding.
7. If necessary, correctly decontaminate, rinse and ventilate
the plant or plant component.
8. If necessary, fit a strainer in front of the valve inlet.
