CAUTION
Hot plant components!
® Risk of burns!
G Only work on plant that has
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).
G Installation work must only be performed
by trained personnel.
G Use appropriate protective gear as
specifi ed in plant operator's guidelines.
Installation location:
CAUTION
G Do not apply external force to the valve.
G Choose the installation location so that
the valve cannot be used as a foothold
(climbing aid).
G Lay the pipeline so that the valve body
is protected against transverse and
bending forces, and also vibrations and
tension.
G Only install the valve between matching
aligned pipes.
Direction of the working medium:
optional.
Mounting position of the valve:
optional.
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.
Installation - Butt weld spigots:
1. Adhere to good welding practices!
2. Disassemble the actuator with the
diaphragm before welding the valve body
into the pipeline (see chapter 11.1).
3. Allow butt weld spigots to cool down.
4. Reassemble the valve body and the
actuator with diaphragm (see chapter
11.4).
Installation - Clamp connections:
G When installing clamp connections,
insert a gasket between the body clamp
and the adjacent piping clamp and join
them using the appropriate clamp fi tting.
The gasket and the clamp for clamp
connections are not included in the scope
of delivery.
Important:
Butt weld spigots /
Clamp connections:
Angle of rotation for welding into
pipeline to enable optimised
draining see brochure "Angle of
rotation for 2/2-way valve bodies"
(on request or
www.gemu-group.com).
Installation - Threaded connections:
G Screw the threaded connections into
the piping in accordance with valid
standards.
