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. If the valve is installed in
the horizontal position, pay attention that the vent hole in the actuator is aligned
horizontally on one side.
To prevent damage, make sure that
•
the valve is installed in the pipe system free of tension and
•
no foreign materials (e.g. tools, bolts, lubricants) are left in the system.
•
If the valve is installed horizontally, the stress on the valve stem seals is
higher than in the vertical installation position. Therefore, support the actuator
and regularly check the valve for leakage.
6.3
Control head
If external valves are connected in a control top with several solenoid valves,
make sure that the control air pressure in the main actuator does not fall below
the operating pressure.
6.4
Valve with Detachable Pipe Connection Elements
This section describes the procedure to fit the valve.
