Samson 3244 - Installing Valve into Pipeline; Testing the Installed Valve

5-6 EB 8026 EN
Installation
Î Before mounting the actuator, determine
which V-shaped port is uncovered rst
when the plug is lifted out of the seat.
Î On mounting the actuator, make sure
that the V-shaped port uncovered rst
faces toward the valve outlet (AB) at the
side.
Î To mount the actuator, proceed as de-
scribed in the associated actuator docu-
mentation.
5.4 Installing the valve into the
pipeline
Premature wear and leakage due to insuf-
cient support or suspension.
Î Support or suspend the valve sufciently
at suitable points.
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.
5.5 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.
Î Drain the process medium from the plant
sections affected as well as from the
valve.
Risk of personal injury due to pressurized
components and as a result of process me-
dium being discharged.
Î Do not loosen the screw of the test con-
nection while the valve is pressurized.
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation or ashing)
may occur during operation caused by the
process medium and the operating condi-
