Installation location:
CAUTION
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 mount the valve between
G
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 bonnet 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
bonnet with diaphragm (see chapter
11.4).
Installation - Clamp connections:
When installing clamp connections,
G
insert a gasket between the body clamp
and the adjacent piping clamp and join
them using the appropriate clamp fitting.
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:
Screw the threaded connections into the
G
piping in accordance with valid standards.
Screw the valve body into the piping, use
G
appropriate thread sealant. The thread
sealant is not included in the scope of
delivery.
Installation - Flange connection:
1. Pay attention to clean, undamaged
sealing surfaces on the mating flanges.
2. Align flanges carefully before installing
them.
3. Centre the seals accurately.
4. Connect the valve flange and the piping
flange using appropriate sealing material
and matching bolting. Sealing material
and bolts are not included in the scope
of delivery.
5. Use all flange holes.
6. Only use connector elements made of
approved materials!
7. Tighten the bolts diagonally!
Observe appropriate regulations for
connections!
