5.3 Preparing the valve
CAUTION
Outdoor installation
Damage due to corrosion!
▷
Provide weather-proof protection to protect the valve against moisture.
1. Thoroughly clean, flush and blow through all vessels, piping and connections.
2. Remove the valve's flange covers before installing it in the piping.
3. Check that the inside of the valve is free from any foreign objects. Remove any
foreign objects.
4. If required, install a strainer in the piping.
5.4 Piping
WARNING
Impermissible piping forces
Leakage from or rupture of the valve body!
▷
Connect the pipes to the valve without transmitting any stresses or strains.
▷
Take structural measures to prevent any piping forces from being transmitted
to the valve.
▷
Avoid mechanical loads beyond normal levels, e.g. piping forces, moments and
vibrations.
CAUTION
Painting pipes and actuator
Valve function impaired!
▷
Protect stem, plastic components and actuator elements prior to applying paint.
▪
For any further work (e.g. construction work, cleaning measures) protect the
valve and the piping against contamination (e.g. by covering it with a tarpaulin).
5.4.1 Flange connection
Fasteners
Only use fasteners, e.g. to DIN EN 1515-4, made of materials approved for the
respective nominal valve size. Always use all flange bolt holes provided when
connecting the valve to the pipe.
