Installation location:
CAUTION
Do not apply external force to the valve.
Choose the installation location so that
the valve cannot be used as a foothold
(climbing aid).
Lay the pipeline so that the valve body
is protected against transverse and
bending forces, and also vibrations and
tension.
Only mount the valve between
matching aligned pipes.
Direction of the working medium:
optional.
Mounting position of the diaphragm 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.
The valves require no further mechanical
modifications or attachments.
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 13.1 "Valve
disassembly (removing actuator from
body)").
3. Allow butt weld spigots to cool down.
4. Reassemble the valve body and the
actuator with diaphragm (see chapter
13.4 "Actuator mounting on the valve
body").
Installation - Flanges:
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!
Installation - Solvent cement spigots:
CAUTION
Damage to the valve body!
Only use solvent cement suitable for
the valve body.
The solvent cement is not included
in the scope of delivery!

1. Apply solvent cement on the outside
of the valve body spigots 1 and on
the inside of the piping connector 2
as specified by the solvent cement
manufacturer.
2. Connect the valve body to the piping.
