Start-up and operation
During the pressure test, make sure the fol-
lowing conditions are met:
–
Detach the control line and seal the
openings at the valve body and the pipe-
line with suitable end plugs. Alternative-
ly, install a shut-off valve in the control
line.
–
Make sure that the pressure rises simulta-
neously upstream and downstream of the
regulator to avoid damaging the balanc-
ing bellows.
–
Do not allow the pressure to exceed the
1.5 times the nominal pressure of the
valve body.
6.1.3 Pressure test
Risk of the operating diaphragm bursting
due to excessive pressure during pressure
testing.
−
The pressure must not exceed the maxi
-
mum permissible pressure by 1.5 times the
pressure rating.
−
Remove the control line from the regulator
and seal the open connection with a blank-
ing plug (accessories: blanking plug 8323-
0030 and seal 8412-0771).
The plant operator is responsible for per
-
forming the pressure test. SAMSON's Af-
ter-sales Service department can support you
to plan and perform a pressure test for your
plant.
Risk of valve damage due to a sudden pres-
sure increase and resulting high flow veloci
-
ties.
Slowly open the shut-off valves.
