6 Assembly and installation
6.1 Safety instructions
Hazardous situations during installation can be avoided by safety-conscious and
proactive behaviour of the personnel.
For installation, the following principles apply:
•
Only qualified personnel are allowed to set-up, install and commission the
component.
•
Ensure that adequate working and traffic areas are available at the place of
installation.
•
Observe the maximum load-bearing capacity of the installation surface.
•
Observe the transport instructions and markings on the part(s) to be
transported.
•
Remove any nails protruding from transport crates immediately after opening
the crate.
•
Under no circumstances should anyone stand under a suspended load.
•
Safety devices of the component may not work effectively during installation.
•
Reliably secure sections of the plant which have already been connected
against inadvertently being switched on.
6.2 Notes on installation
The valve can be installed in any position. Care must be taken to ensure that the
valve housing and the pipe system can drain properly.
To prevent damage, make sure that
•
the valve is installed in the pipe system free of tension.
•
no foreign materials (e.g. tools, bolts, lubricants) are left in the system.
•
with all pneumatic actuators that are used in a vertical pipe, the brackets are
facing upwards.
6.3 Butterfly Valve with Welding Flange Design
This section describes the welding procedure for the butterfly valve.
Notice!
Damage caused by welding
The butterfly valve can be damaged by distortion due to welding and when
the position of the grooves is altered.
► Only weld the butterfly valve in assembled condition without gasket and
disk.
► To ensure that a proper weld is formed when the valve is welded into the
pipe, make sure that the root side of the weld is protected against oxidation
by forming gas.
