Mount control cone
→ Placecontrolconeonthespindle.
→ Alignboreholesinthecontrolconeandspindle.
→ Supportcontrolconeonthecylindricalpartusingaprismor
somethingsimilar.
→ Setupthespring-typestraightpinandcarefullyhammeritin.
→ Centrethespring-typestraightpinwiththespindleaxis.
Install actuator (with control unit) on the valve body
→ Replacethesealifnecessary.
WARNING!
Risk due to incorrect lubricants.
Unsuitablelubricantmaycontaminatethemedium.Thereisa
riskofexplosioninoxygenapplications.
▶ Forspecicapplications,e.g.oxygenoranalysisapplica-
tions,useapprovedlubricantsonly.
→ Beforere-installation,greasenipplethreadoftheactuator
(e.g.usingKlüberpasteUH196-402fromKlüber).
NOTE!
