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.
Tip
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. Depressurize the pipeline section and
valve.
5. Rework any parts that leak and repeat
the leak test.

NOTICE
!
Risk of valve damage due to a sudden pres-
sure increase and resulting high flow veloci-
ties.
− Slowly open the shut-off valves.
During the pressure test, make sure the fol-
lowing conditions are met:
Î Do not allow the pressure to exceed the
1.5 times the pressure rating of the valve
body.
Î The regulator must remain open.
Therefore, set the maximum set point to
ensure that the regulator does not close.
Alternatively, detach the control line and
seal the opening at the valve body with a
G ¼ stopper (accessories: stopper 8323-
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.
