Start-up and operation
– Bellows actuator DN65 to 100
Remove the crossbeam (8) from the
valve.
Unscrew the pillars (8.1).
Screw the pillars into the threaded holes
(8.3)oftheactuatorangeasfarasthey
will go.
Push the actuator with actuator stem (11)
onto the spigots of the bellows (5.1).
Fasten the pillars (8.1) with the nuts (8.2)
ontothevalveange.Observethetight-
eningtorquesspeciedinsection7.5.
7. Mount the control line (17) onto the valve
and actuator.
For steam or liquids above 150°C in-
stallthecompensationchamberandllit
with the process medium. Observe the
tighteningtorquesspeciedinsec-
tion7.5.
8. Dependingontheeldofapplication,
allow the valve to cool down or heat up
to reach ambient temperature before
start up.

pipeline after the valve has been in-
stalled.
6.1.2 Pipeline ushing
SAMSONWerecommendushingthepipe-
line with installed regulator before start-up.
Î Unscrewthecontrolline(seeFig.3).
Î SealthevalvebodywithG¼stoppers.
Î Observethemeshsizeoftheupstream
strainerforthemaximumparticlesize.
Use strainers to suit the process medium.
Î Check the strainer for dirt each time the
pipelineisushedandcleanit,ifneces-
sary.
If the regulator malfunctions due to clogging
afterushingthepipeline,proceedasde-
scribedinTable9.
