5. Installation
WARNING
Installation works
There is a risk of injury if this prod-
uct is not properly installed, disas-
sembled and put into operation.
•
Make sure the personnel has received
the appropriate training.
•
Observe the safety instructions in
„Chapter 2. Safety“.
NOTE
Check the technical parameters, in par-
ticular pressure and temperature, and
the electrical voltage of the control valve
before installing or commissioning the ac-
tuator.
The piping system and control system must
be installed properly.
Make sure the valve is moving in the cor-
rect direction of rotation. Always mount
the valves into the pipeline without tensing
them.
The valve is not designed to absorb addi-
tional pipe connection forces. In the case of
large valves, it is recommended to support
the pipeline.
5.1 Installation conditions
The minimum space requirement can be
found in the dimensional drawing (
“Chapter
14. Annex/Technical data”).
5.2 Before installation
Observe the following points before instal-
lation:
•
The dew point of the control medium
must be min. 10 °C lower than the low-
est operating temperature! The max.
temperature of the control medium is
45 °C!
For other valve types, in particular large-vol-
ume valves with low torque requirement, the
operating conditions of the actuator must
be agreed with the manufacturer. We will be
delighted to advise you.
5.3 Installation of ball valve
5.3.1 Preparing for installation
These steps are to be carried out both when
mounting a ball valve with welding ends and
with threaded connection.

Gently clamp the fitting into a vise.
Leave the supplied protective cov-
ers on the connection ends to pre-
vent damage to the connection ends.
