11 Installation, operation and
adjustments
Prior to installation:
Ensure that valve body and isolating
G
diaphragm material are appropriate
and compatible to handle the working
medium.
See chapter 6 "Technical data".
11.1

Installing the valve

WARNING
The equipment is subject to pressure!
® Risk of severe injury or death!
Only work on depressurized plant.
G
WARNING
Corrosive chemicals!
® Risk of caustic burns!
Wear appropriate protective
G
gear when installing.
CAUTION
Hot plant components!
® Risk of burns!
Only work on plant that has
G
cooled down.
CAUTION
Never use the valve as a step or an aid
for climbing!
® This entails the risk of slipping-off or
damaging the valve.
CAUTION
Do not exceed the maximum
permissible pressure!
® Take precautionary measures to
avoid possible pressure surges (water
hammer).
Installation work must only be performed
G
by trained personnel.
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
(climbing aid).
Lay the pipeline so that the valve body
G
is protected against transverse and
bending forces, and also vibrations and
tension.
Only install the valve between matching
G
aligned pipes.
Direction of the working medium:

The fl ow direction is indicated by an
arrow on the valve body:
GEMÜ 563
Installation position of the valve:

For valves with a regulating cone we
recommend to mount the actuator
vertically upright or vertically down to
optimise the service life.
Installation:
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 plant or plant component.
3. Secure against recommissioning.
4. Depressurize the plant or plant
component.
5. Completely drain the plant (or plant
component) and let it cool down until
the temperature is below the media
vaporization temperature and scalding
can be ruled out.
6. Correctly decontaminate, rinse and
ventilate the plant or plant component.
