Mounting and start-up
5 Mounting and start-up
SAMSON valves are delivered ready for
use. The valve and actuator are delivered
separately and must be assembled on site.
The procedure to mount and start up the
valve are described in the following.
We recommend first installing the valve into
the pipeline and mounting the actuator after-
wards.
Risk of valve damage due to excessively high
or low tightening torques.
Observe the specified torques on tightening
control valve components. Excessively tight-
ened torques lead to parts wearing out
quicker. Parts that are too loose may cause
leakage.
5.1 Installing the valve into the
pipeline
For medium temperatures above 150 °C only
the dark gray graphite seals supplied with
the valve are to be used. Do not use the UDP
seals available as accessories as they are
only suitable for temperatures up to 150 °C.
5.1.1 Checking the installation
conditions
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).
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
