Specic conditions of use
5.2 Solenoid coil with cable outlet
ThesolenoidcoiltypeAC10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. Thesolenoidcoilconsistsof:
• coilwinding,
• coilhousing(madefromepoxy),
• electricalconnectioncable,
• bridgerectier.
Alternatingcurrentordirectcurrentcontrolispossible.
ThesolenoidcoiltypeAC10isavailableinarangeofratingsdistributed
across2framesizes.Theinterfacebetweenthecoilandvalveisiden-
ticalforbothframesizes.
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in
theconnectioncable.
5.3 Solenoid coil with terminal box
Thedesignofthesolenoidcoilisidenticaltothedescriptionunder
“5.2”,howeveraterminalboxisalsoinstalledhere(see“Fig.2”).A
connectionsetforadditionalpotentialequalisationisenclosedwith
theterminalbox;observethespecicationsinchapter“8.2”.

▶Fluidhousingsmadeofbrassmustnotbeusedinatmospheres
containingacetylene.
6.2 Block assembly
Valveblocksarepreferablymadeupsothatallunitshavethesame
coilpowerconsumption.Ifdierentcoilpowerconsumptionvalues
areused in a singlevalveblock,thenthetechnicaldataforthe
coilwiththehighestpowerratingmustbeusedtodeterminethe
temperatureclass.Inthiscasetheambienttemperaturemustbe
nohigherthan+40°C(+104°F).

beusedatanytime.
Thesolenoidcoilsdesignedforindividualinstallationmaynotbe
usedforblockassembly.
Thesolenoidcoilsdesignedforblockassemblyaresuitablefor
bothblockassemblyandforindividualinstallation.
6.4 Operating temperature range
Observetheoperatingtemperaturerangespeciedintheelectrical
