5.2 Function
ThesolenoidcoiltypeAC08isanelectromagneticvalveactuator
forvariousBürkertvalves.Asaso-calledtop-mountedcoil,itis
separated100%fromthevalve.Thevalveisaclosedsystemeven
ifthecoilisremoved.
Alternatingcurrentordirectcurrentcontrolispossible.
Thecoilisplacedoverthecoreguidetubeofthevalveandattached
withanut.Itispositivelylockedtopreventturningrelativetothe
valve.
Theelectricalconnectioncableexitsperpendiculartothecoilaxis.
Thecableispermanentlyintegratedinthecoil.Theunionnutisnot
designedtoberemoved.
Anelectricalcontactismadebetweenthemetalcomponentsofthe
valveandthecoilattheinterfacebetweenthecoilandthevalve.All
metalcomponentsmustbegroundedviatheprotectiveconductor
