5.4.1 Leak test
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.
Our after-sales service can support you to
plan and perform a leak test for your plant.
1. Slowly open the shut-off valve installed
upstream of the regulator.
2. Apply the required test pressure.
3. Check the regulator for leakage to the at-
mosphere.
4. Depressurizethepipelinesectionand

5. Rework any parts that leak and repeat
the leak test.
5.4.2 Pressure test
The plant operator is responsible for
performing the pressure test. SAMSON's
After-sales Service can support you to plan
and perform a pressure test for your plant.
Tip
Note
Risk of valve damage due to a sudden pres-
sure increase and resulting high ow veloci-
ties.
− Slowly open the shut-off valves.
During the pressure test, make sure the fol-
lowing conditions are met:
Î Donotallowthepressuretoexceedthe
1.5 times the pressure rating of the valve
body.
Î The regulator must remain open.
Therefore,setthemaximumsetpointto
ensure that the regulator does not close.
Alternatively, detach the control line and
seal the opening at the valve body with a
G¼stopper(accessories:stopper8323-
0030 and seal 8412-0771).
Î Make sure that the pressure rises simulta-
neously upstream and downstream of the
regulator to avoid damaging the balanc-
ing bellows.
