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.
– Donotallowthepressuretoexceedthe
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 ow veloci-
ties.
Slowly open the shut-off valves.
