5.4.1 Leakage
The plant operator is responsible for per-
forming the leak test and selecting the test
method. The leak test must comply with the
requirements of the national and internation-
al standards that apply at the site of installa-
tion.
SAMSON's After-sales Service can support
you to plan and perform a leak test for your
plant.
Î All required control lines are connected
to the actuator and are not shut off.
1. Install the regulator into the pipeline (see
the 'Installation' section).
2. Apply the required test pressure.
3. Check the regulator for leakage to the at-
mosphere.
4. Depressurize the pipeline section and
valve.
5. Rework any parts that leak and repeat
the leak test.
Tip
Risk of personal injury due to process me-
dium escaping.
Î Do not start up the regulator until all
parts have been mounted.
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-
tions.
Î Wear hearing protection when working
near the regulator.
Risk of burn injuries due to hot or very cold
components and pipelines.
Depending on the process medium, valve
components and pipelines may get very hot
or cold and cause burn injuries.
