Installation
5 Installation
The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
Crush hazard arising from moving parts.
The valve's segmented ball turns in the valve
body which can lead to crush injuries to
hands or fingers if they are inserted into the
valve.
Î
Do not insert hands or fingers into the
valve body.
Î
Before working on the control valve, re -
lease any energy (in the actuator) which
causes the valve shaft to move (e.g. also
the spring compression).
Î
Before working on the control valve, dis -
connect and lock the pneumatic air sup-
ply as well as the control signal.
Î
Disconnect the supply voltage before
performing any work on the control
valve.
Î
Do not impede the rotary motion of the
segmented ball by inserting objects into
its path.
Î
Before attempting to unblock a segment-
ed ball after it has become blocked (e.g.
due to seizing up after remaining in the
same position for a long time), release
any energy (in the actuator) which caus
-
es the valve shaft to move.
5.1 Installation conditions
Work position
The work position for the control valve is the
front view looking onto the operating con-
trols (including valve accessories).
Plant operators must ensure that, after instal-
lation of the device, the operating personnel
can perform all necessary work safely and
easily access the device from the work posi-
tion.
Pipeline routing
The inlet and outlet lengths vary depending
on several variables and process conditions
and lie within the responsibility of the plant
engineering company.
To ensure that the valve functions properly,
proceed as follows:
Î
Install the valve free of stress and with the
least amount of vibrations as possible.
Read ‘Mounting position’ and ‘Support
or suspension’ in this section.
Î
Install the valve allowing sufficient space
to remove the actuator and valve or to
perform service and repair work on
them.
Mounting position
We recommend installing the valve with the
valve shaft in the horizontal position into the
pipeline.
If required, the valve can also be installed
into the pipeline with the valve shaft in the
vertical position and the actuator on top of
the valve.
