Installation
Î BellowsactuatorDN65to100
− Remove the crossbeam (8) from the
valve.
− Unscrew the pillars (8.1).
− Screw the pillars (8.1) into the threaded
holes(8.3)oftheactuatorangeasfar
as they will go.
− Insert the actuator stem (11) into the trav-
el stop cap with cotter pin (20).
− Fasten the pillars (8.1) with the nuts (8.2)
ontothevalveange.Observethetight-
eningtorquesspeciedintheAnnex.
7. Lock the cotter pin (20) on the travel stop
cap.
8. Mount the control line (17) onto the valve
and actuator. Observe the tightening
torquesspeciedintheAnnex.
Î With diaphragm actuators
− 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theAn-
nex.
9. Slowly open the shut-off valves in the
pipeline after the valve has been in-
stalled.
5.3.2 Cleaning the pipeline
Werecommendadditionallyushingthe
pipeline with installed regulator before start-
up.
Î Unscrew the control line (17) from the
valve body.
Î SealthevalvebodywithG¼stoppers
(accessories: stopper 8323-0030 and
seal 8412-0771).
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 the ‘Malfunctions’ section.
