10 Assembly and operation

Prior to installation:
Ensure that valve body and diaphragm
G
material are appropriate and compatible
to handle the working medium.
Check the suitability prior to the
G
installation.
See chapter 5 "Technical data".
10.1 Assembling
the diaphragm valve
WARNING
The equipment is subject to
pressure!
® Risk of severe injury or death!
Only work on depressurized
G
plant.
WARNING
Corrosive chemicals!
® Risk of caustic burns!
Wear appropriate protective
G
gear when assembling.
WARNING
Hot plant components!
® Risk of burns!
Only work on plant that has
G
cooled down.
WARNING
Actuator under spring
pressure.
® Risk of severe injury or death!
Only open the actuator under
G
a press.
CAUTION
Never use the valve as a step or an aid
for climbing!
® This entails the risk of slipping-off or
damaging the valve.
Do not exceed the maximum
permissible pressure!
® Take precautionary measures to
avoid possible pressure surges (water
hammer).
Assembly work may only be performed
G
by trained specialised staff .
Use appropriate protective gear as
G
specifi ed in plant operator's guidelines.

Installation location:

Do not apply external force to the valve.
G
Choose the installation location so that
G
the valve cannot be used as a foothold.
Lay the pipeline so that the valve body
G
is protected against transverse and
bending forces, and also vibrations and
tension.
Only mount the valve between
G
matching aligned pipes.
Direction of the working medium:

optional.
Mounting position of the diaphragm valve:

optional.
Assembly:
1. Ensure the suitability of the valve for
each respective use. The valve must
be appropriate for the piping system
operating conditions (medium, medium
concentration, temperature and
pressure) and the prevailing ambient
conditions. Check the technical data of
the valve and the materials.
2. Shut off pressure line or process
line.
3. Secure against re-commissioning.
4. WARNING Depressurize the plant or
plant component.
