Mounting position:

For valves with a regulating cone we
recommend to mount the actuator
vertically upright (preferred) or vertically
down to optimize the service life.
Direction of the working medium:

Flow direction:
G*
Flow under the seat*
* Preferred fl ow direction with
incompressible liquid media and steam
to avoid "water hammer".
The fl ow direction is indicated by an

arrow on the valve body:
Flow under the seat
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.

sealing surfaces on the mating fl anges.
2. Align fl anges carefully before installing
them.
3. Centre the seals accurately.
4. Use all fl ange holes.
5. Connect the valve fl ange and the piping
fl ange using appropriate sealing material
and matching bolting (sealing material
and bolts are not included in the scope
of the delivery).
Tighten the bolts diagonally!
6. Only use connector elements made of
approved materials!
Observe appropriate regulations for
