Samson 3222 Series - Installing the Valve into the Pipeline; Mounting the Actuator Onto the Valve

5-4 EB 5866 EN
Installation
5.3.1 Installing the valve into
the pipeline
Risk of valve damage due to work being
carried out by personnel not qualied for
such tasks.
The plant operator or specialist company
performing the welding is responsible for the
selection of the welding procedure and the
actual welding operations on the valve. This
also applies to any required heat treatment
to be performed on the valve.
Î Only allow qualied welding personnel
to carry out welding operations.
1. Close the shut-off valves in the pipeline
at the inlet and outlet of the plant section
while the valve is being installed.
2. Prepare the relevant section of the pipe-
line for installing the valve.
3. Remove any protective caps from the
valve ports before installing the valve.
4. Lift the valve to the site of installation (see
the 'Lifting the valve' section). Observe
the ow direction through the valve. The
arrow on the valve indicates the direction
of ow.
5. Version with anges: make sure that the
correct ange gaskets are used.
Version with threaded ends (female/
male thread) and anges: fasten the
valve to the pipeline free of stress.
Version with welding ends: weld the
valve free of stress into the pipeline.
6. Attach a support or suspension on the
valve, if necessary, to avoid premature
wear and leakage.
5.3.2 Mounting the actuator
onto the valve
Depending on the version, SAMSON control
valves are either delivered with the actuator
already mounted on the valve or the valve
and actuator are delivered separately. When
delivered separately, the valve and actuator
must be assembled together on site.
Î To mount the actuator, proceed as de-
scribed in the associated actuator docu-
mentation:
