6 Installation
6.1 General
To avoid leakage, deformation or rupture of
the body, the piping should be laid out in such
awaythatnothrustorbendingforcesacton
thevalvebodies(100)whentheyareinstalledandoperational.
Only remove the covers from the connection
endsjustbeforeinstallation.Thesealingfaces
of the flanges must be clean and undamaged.
The gaskets at the connecting flanges must be
precisely entered. Use only joints and gaskets of
approved materials. All holes provided in the flanges
must be used for the flange connection.
When painting the pipes, do not apply paint to bolts
andstem(200).Ifconstructionworkisstillinprogress,
the valves must be protected against dust, sand and
buildingmaterialetc.(coverwithsuitablemeans).
Donotusevalvehand-wheelsasfootholds!
Valvesandpipesusedforhigh(>500C)orlow(<00C)
temperaturesmusteitherbettedwithaprotective
insulation,ortheremustbewarningsignsinstalled
showingthatitisdangeroustotouchthesevalves.
If a valve is used as end-valve in a pipe, this
valve should be protected against unauthorized or
unintentionalopeningto preventpersonalinjuryor
damage to property.
