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 dimension drawing or dimen-
sion table (
„Chapter 17. 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
Fig. 5-1 Mounting a ball valve in pipeline
1. Slide the flange ball valve between the
flanged ends of the pipeline.
2. Make sure that the flange ball valve is
seated correctly.
3. Make sure that there are no dirt or other
particles on the flanges or the ball.
4. After checking the correct seat (no ten-
sion, offset, etc.) of the flange ball valve,
it can be installed crosswise in the pipe-
line using hexagon screws. Never use
the valve itself as a lever!
