11 Installation and connection
Prior to installation:
G Ensure that valve body and seal 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!
G Only work on depressurized plant.
WARNING
Corrosive chemicals!
® Risk of caustic burns!
G Wear appropriate protective
gear when installing.
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 mount the valve between
matching aligned pipes.
