Mounting and start-up

5 Mounting and start-up
SAMSON valves are delivered ready for
use. Proceed as follows to mount and start
up the valve.
NOTICE
!
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.
Observe the specified tightening torques
(u AB 0100).
NOTICE
!
Risk of valve damage due to the use of un‑
suitable tools.
Only use tools approved by SAMSON
(u AB 0100).

5.2 Installing the valve into the
pipeline
5.2.1 Checking the installation
conditions
Pipeline routing
The inlet and outlet lengths vary depending
on the process medium. To ensure the control
valve functions properly, follow the installa‑
tion instructions given below:
Î Observe the inlet and outlet lengths (see
Table 11). Contact SAMSON if the valve
conditions or states of the medium pro‑
cess deviate.
Î Install the valve free of stress and with the
least amount of vibrations as possible. If
necessary, attach supports to the valve.
Î Install the valve allowing sufficient space
to remove the actuator and valve or to
perform service and repair work on
them.
Mounting orientation
Generally, we recommend installing the
valve with the actuator upright and on top of
the valve.
Î Contact SAMSON if the mounting posi‑
tion is not as specified above.
Support and suspension
Depending on the valve version and mount‑
ing position, the control valve and pipeline
must be supported or suspended. The plant
engineering company is responsible in this
case.
