2 INTENDED USE
Non-authorized use of the electromotive diaphragm valve
of Types 3323, 3324 and 3325 may be a hazard to people,
nearby equipment and the environment.
The electromotive diaphragm valve is designed to control the
ow of liquid and gaseous media.
▶Standardmodeldevicesmustnotbeusedinthepotentially
hazardousarea.TheydonothaveaseparateExtypelabel
whichindicatesapprovalfortheexplosion-proofarea.
▶Thesurfacesofthedevicemustnotbecleanedwithalkaline
cleaningagents.
▶Ifthevalvepositionisrelevantasregardssafetyintheevent
ofapowerfailure:Useonlythosedeviceswhichhavethe
SAFEPOSenergy-pack(optionalenergypack).
▶Useaccordingtotheauthorizeddata,operatingconditions,
andconditionsofusespeciedinthecontractdocuments
andoperatinginstructions.
▶Protectthedeviceagainstharmfulenvironmentalinuences
(e.g.radiation,airhumidity,vapors,etc.)!Ifindoubt,consult
therelevantsalescompany.
Use the device
▶onlyinconjunctionwiththird-partydevicesandcomponents
recommendedandauthorizedbyBürkert.
▶Useonlywheninperfectconditionandalwaysensure
properstorage,transportation,installationandoperation.
▶Useonlyasintended.
3 BASIC SAFETY INSTRUCTIONS
Thesesafetyinstructionsdonotconsideranycontingencies
orincidentswhichoccurduringinstallation,operationand
maintenance.
Theoperatorisresponsibleforobservingthelocation-specic
safetyregulations,alsowithreferencetothepersonnel.
Risk of injury from high pressure.
▶Beforeworkingonthesystemordevice,switchothepres-
sureandventordrainlines.
If switched on for a prolonged time, risk of burns or re due
to hot device surface.
▶Keepthedeviceawayfromhighlyammablesubstances
andmediaanddonottouchwithbarehands.
Risk of crushing due to mechanically moving parts.
▶Performinstallationworkonthepressurepiece,diaphragm
andvalvebodyonlywhentheyhavebeenisolatedfromthe
powersupply.
DeviceswithSAFEPOSenergy-pack:Completelydrain
SAFEPOSenergy-pack.WaituntilLEDilluminatedringgoes
out;theLEDstatusmustnotbeinLED omode.
▶Keepclearoftheopeningsinthevalvebody.
Danger due to an uncontrolled process in the event of a
power failure.
IfdevicesdonothavetheoptionalSAFEPOSenergy-pack,the

7 INSTALLATION OF THE VALVE
WARNUNG
Risk of injury from improper assembly.
▶Theassemblymaybecarriedoutonlybytrainedtechnicians
andwiththeappropriatetools.
▶Securesystemagainstunintentionalactivation.
▶Afterinstallation,ensurethattheprocessisrestartedina
controlledmanner.Observesequence!
1.Applysupplyvoltage.
2.Chargethedevicewithmedium.
CAUTION
Riskofinjuryduetoaheavydevice.
Aheavydevicecanfalldownduringtransportorduringinstal-
lationandcauseinjuries.
▶Transport,installanddismantleaheavydevicewiththehelp
ofanotherperson.
▶Useappropriatetools.
NOTE!
Note the following when installing the device in the plant.
The device and the relief bore must be accessible to allow
inspectionandmaintenancework.

Installation of the valve
Type 3323, 3324, 3325
7.1 Installation position of the diaphragm
valves
Theinstallationpositionofthediaphragmvalvevariesdepending
onthevalvebody.
Oneoftheboresinthediaphragmsocket,formonitoring
leakage,mustbeatthelowestpoint.
7.1.1 Installation position of 2-way body
Installation position:anyposition,preferablywiththeactuator
facingup.
Ensuring self-drainage:
→Installvalvebodyatanangleα=10°–55°inclinedtowards
thehorizontal.
Thisisindicatedbyamarkonforgedandcastbodieswhich
mustfaceupwards(12o’clockposition,see“Fig.10”).
Angleα:10°–55°

connection
NOTE!
Damage to the diaphragm.
▶Topreventdamage,thevalvemustbeinMANUALoperating
stateduringinstallation.
DevicesaredeliveredwiththeMANUALoperatingstatepreset.
Installation prerequisites:
Pipelines: Ensurethatthepipelinesarealigned.
Preparation: Supportandalignpipelines.Toensurethatthe
pipelineisself-draining,observeaninclination
angleof1°...5°.
DANGER
Risk of injury from high pressure!
▶Beforeworkingonthesystem,switchothepressureand
ventordrainlines.
→Connectvalvebodytopipeline.
Ensureinstallationisde-energizedandlow-vibration.
Holding device
Toprotectthevalveactuatorfromdamageduetoforces
andoscillations,aholdingdeviceisrecommended.This
isavailableasanaccessory.Seeoperatinginstructions
onthehomepagewww.buerkert.de.
→Connectthedeviceelectrically.
Thepositionoftheconnectionscanbealignedbyrotating
theactuatorthrough360°.Foradescriptionseechapter“7.5
Rotatingtheactuator”.
Adescriptionoftheelectricalconnectioncanbefoundin
chapter“8Electricalinstallation”.
7.2.1 Following installation
→Whentheoperatingvoltagehasbeenapplied,maketherequired
basicsettingsandadjustmentsfortheelectromotivediaphragm
valve.Foradescriptionseechapter“9Start-up”.
NOTE!
Damage to the diaphragm.
▶Topreventdamage,rstruntheM.Q0.TUNEfunctionafter
makingtheelectricalconnection.Onlythensettheoperating
statetoAUTOMATIC.
7.3 Installation of devices with welded
connection
NOTE!
Damage to the diaphragm.
▶Weldthedeviceintothepipelineonlywiththeactuator
removed.
▶Topreventdamage,thedevicemustbeinMANUALoper-
atingstateduringinstallation.Theactuatormustbeinthe
“Valveopen”position.
Observethenationalregulationsforthequalicationofwelders
andforperformingweldingwork.

1. Welding tank bottom body onto the tank:
ATTENTION!
Before welding, note the following:
▶Use only welding material which is suitable for the tank
bottom body.
▶The tank bottom valve must not collide with any other
installation part. The actuator must be easy to install and
remove.
2. Welding tank bottom body into the pipeline:
→Weldintankbottombody.
Ensureinstallationisde-energizedandlow-vibration.
After welding in the valve body:
Installthediaphragmandtheactuator.
