6 Assembly and installation
6.1 Safety instructions
Dangerous situations during assembly can be avoided by safety-conscious and
proactive behaviour of the staff.
For installation, the following principles apply:
• Only properly qualified staff is allowed to install, assemble and set the valve
into operation.
•
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.
•
During assembly, the valve safety devices might not be working effectively.
• 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
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.
