5.3.3 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.
Premature wear and leakage due to insuf-
cient support or suspension.
Î Support or suspend the valve sufciently
at suitable points.
a) Version with anges
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 the protective caps from the
valve ports before installing the valve.
4. Lift the valve using suitable lifting equip-
ment to the site of installation (see the
'Lifting the valve' chapter). Observe the
ow direction through the valve. The ar-
row on the valve indicates the direction
of ow.
5. Make sure that the correct ange gaskets
are used.
6. Bolt the pipe to the valve free of stress.
7. Attach a support or suspension on the
valve, if necessary.
b) Version with welding ends
1. Proceed as described above under “Ver-
sion with anges”, steps 1 to 4.
2. Completely retract the actuator stem to
protect the plug from sparks during weld-
ing.
3. Weld the valve free of stress into the
pipeline.
4. Attach a support or suspension on the
valve, if necessary.
5.4 Testing the installed valve
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Valves and pipelines are pressure equipment
that may burst when handled incorrectly.
Flying projectile fragments or the release of
process medium under pressure can cause
serious injury or even death.
Before working on the control valve:
Î Depressurize all plant sections affected
and the valve (including the actuator).
Release any stored energy.
