Type 3320, 3321
2 INTENDED USE
Improper use of the electromotive 2/2 way Type 3320 and 3321
valve may be dangerous for people, nearby equipment and the
environment.
The electromotive 2/2-way Type 3320 and 3321 valve is
designed to control the ow of liquid and gaseous media.
▶Standarddevicesmustnotbeusedinthepotentiallyexplo-
sivearea.Theydonotpossesstheseparate“Ex”type
labeldenotingtheapprovalforuseinpotentiallyexplosive
environments.

thesurfaceofthedevice.
▶Ifthepositionofthevalvehasabearingonsafetyconcerns
intheeventofapowerfailure:Onlyusedevicesthathavea
SAFEPOS energy-pack (optional energy-pack).
▶When using the device, observe the authorised data, opera-
tingconditionsanddeploymentconditionsspeciedinthe
contract documents and in the operating instructions.
▶Protectdevicefromharmfulenvironmentalinuences!(e.g.

3 BASIC SAFETY INSTRUCTIONS
Thesesafetyinstructionsdonottakeintoaccountanyunforeseen
circumstances and events which occur during installation, ope-
rationandmaintenance.Theoperatorisresponsibleforobserving
thelocation-specic safetyregulations, also withreferenceto
personnel.
Risk of injury from high pressure.
▶Beforeworkingonthedeviceorsystem,switchothepres-
sure and vent or empty the lines.
Danger of burns and risk of re.
Followinganextendeddutycycleorasaresultofahotmedium,
thesurfaceofthedevicemaybecomehot.
▶Only touch the device when wearing protective gloves.
▶Keepthedeviceawayfromhighlyammablesubstances
and media.
Risk of crushing by mechanically powered parts.
▶Installation work on the swivel plate, diaphragm and valve body
mustonlybeperformedwhileelectricallyisolated.
▶For devices with SAFEPOS energy-packs: Ensure that the
SAFEPOSenergy-packisfullydischarged.WaituntiltheLED
ringisnolongerlitandensurethattheLEDstatusisnotin
LED o mode.
▶Donotreachintotheopeningsofthevalvebody.
Risk of uncontrolled process in the event of a power failure.
For devices without the optional SAFEPOS energy-pack, the
valvewillnotstopinadenedpositionintheeventofapower
failure.
▶Ifthepositionofthevalvehasabearingonsafetyconcerns
intheeventofapowerfailure:Onlyusedevicesthathavea
SAFEPOS energy-pack (optional energy-pack).
▶Selectavalvepositionthatissafeinrespectoftheprocess
using the DIP switch.
Danger due to loud noises.
▶Depending on the operating conditions, the device may generate
loudnoises.Moredetailedinformationonthelikelihoodofloud
noisesisavailablefromtherelevantsalesoce.
▶Wearhearingprotectionwheninthevicinityofthedevice.
Discharge of medium if packing gland worn.
▶Reliefboremustberegularlyinspectedforanymediumleakages.
▶Ifmediumisleakingfromthereliefbore,thepackingglandmust
bereplaced(seechapter“Maintenance”).
▶Ifthemediumishazardous,securetheareaaroundtheleakage
to prevent risks.
General hazardous situations.
Topreventinjuries,observethefollowing:
▶Inpotentiallyexplosiveenvironmentsthedevicemustonlybe
usedinaccordancewiththespecicationsontheseparate
“Ex”typelabel.
▶Theadditionalinformationandsafetyinstructionsrelatingto
potentiallyexplosiveatmospheresenclosedwiththedevice
or the separate operating instructions relating to potentially
explosiveatmospheresmustbeheededwhenusingthe
device.
▶Inpotentiallyexplosiveatmospheres,onlyusedeviceswitha

7 INSTALLING THE VALVE
WARNING!
Risk of injury due to improper installation.
▶Installation may be carried out by trained technicians only
with the appropriate tools.
▶Secure the system against unintentional activation.
▶Afterinstallation,ensurethattheprocessisrestartedina
controlledmanner.Observethesequence.
1. Connect supply voltage.
2. Charge the device with medium.
CAUTION!
Risk of injury due to heavy device.
During transportation or installation work, the devicemayfall
down and cause injuries.
▶Transport,installandremoveheavydevicewiththeaidofa
second person only.
▶Usesuitabletools.
WARNING!
The following must be heeded when installing the device in
the system.
Thedeviceandreliefboremustbeaccessibleforinspections
and maintenance work.

7.1.2 Installation
DANGER!
Risk of injury from high pressure.
▶Beforeworkingonthesystem,switchothepressureand
vent or empty the lines.
WARNING!
Risk of crushing by mechanically powered parts.
▶Donotreachintotheopeningsofthevalvebody.
→Connect valve body to pipeline.
Ensure that there is no voltage present and minimal vib-
ration during installation.

7.2 Installation of devices with welded
connections
The device must not be welded into the pipeline while the actuator
isstillinstalled.Theinstallationisdividedintothefollowingsteps:
1. Prepare the actuator disassembly.
2. Disassemble actuator.
3. Weld the valve body into the pipeline.
4.Mountingactuatoronthevalvebody.
7.2.1 Prepare the actuator disassembly.
WARNING!
Damage to valve body, seat seal or diaphragm.
To avoid damage, the valve must be open when the actuator is
disassembled.
→Ifthevalveisclosed:Openthevalvewiththemechanical
manual override. See chapter “12.2 Actuating the valve
mechanically” on page 40.
WARNING!
Risk of crushing by mechanically powered parts.
▶Switchothesupplyvoltage.
▶FordeviceswithSAFEPOSenergy-packs:EnsurethattheSAF-
EPOSenergy-packisfullydischarged.WaituntiltheLEDring
isnolongerlitandensurethattheLEDstatusisnotinLEDo
mode.
▶Donotreachintotheopeningsofthevalvebody.
7.2.2 Disassemble actuator
→Clamp valve body into a holding device.
→Place on the body connection with a suitable open-end
wrench.
Donotuseanytoolsforunscrewing,whichcould
damage the body connection (e.g. pipe wrench).
→Unscrewactuatorfromthevalvebody.

DANGER!
Risk of injury from high pressure.
▶Beforeworkingonthesystem,switchothepressureand
vent or empty the lines.
WARNING!
The electronics assembly in the actuator will be damaged by
the eects of heat.
•Theactuatormustberemovedbeforethevalvebodyis
welded in.
→Weld the valve body into the pipeline.
Ensure that there is no voltage present and minimal vib-
ration during installation.
7.2.5 Mounting actuator on the valve body
→Beforeinstallationtheactuator,checkwhethertheseal
forthevalvebodyispresentandundamaged.
