The work described in this section is only to
be performed by personnel appropriately
qualied to carry out such tasks.
5.1 Installation conditions
Work position
The work position for the control valve is the
front view looking onto the operating con-
trols (including valve accessories).
Plant operators must ensure that, after instal-
lation of the device, the operating personnel
can perform all necessary work safely and
easily access the device from the work posi-
tion.
Pipeline routing
To ensure that the valve functions properly,
proceed as follows:
Î Do not exceed the maximum permissible
ow velocity.
The plant operator is responsible for deter-
mining the maximum permissible ow veloci-
ty. Our after-sales service can support you to
determine the ow velocity for your plant.
Î Install the valve free of stress and with the
least amount of vibrations as possible.
Read information under ‘Mounting posi-
tion’ and ‘Support or suspension’ in this
section.
Î Install the valve allowing sufcient space
to remove the actuator and valve or to
perform service work on them.
Mounting position
Generally, we recommend installing the
valve with the actuator upright and on top of
the valve.
For versions for water, oil and other liquids,
the actuator must not be suspended down-
wards (see Fig.5-1).
In the following versions, the valve must be
installed with the actuator on top in a hori-
zontal pipeline:
− Version for water above 150°C and
steam
Î Contact SAMSON if the mounting posi-
tion is not as specied above.
