2 INTENDED USE
Non-authorized use of the electromotive 2/2-way valve,
Types 3320 and 3321, may be a hazard to people, nearby
equipment and the environment.
The electromotive 2/2-way valve, Types3320 and 3321, is
designed to control the ow of liquid and gaseous media.
▶Standarddevicesmustnotbeusedinthepotentiallyhazard-
ous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

3.Weldvalvebodyintothepipeline.
4.Mountactuatoronthevalvebody.
7.3.1 Preparing removal of the actuator
NOTE!
Damage to valve body, seat seal or diaphragm.
Topreventdamage,thevalvemustbeopenwhenremoving
theactuator.
→Ifthevalveisclosed:Openthevalveusingthemechanical
manualcontrol.“12.2Actuatingvalvemechanically”.
WARNING
Risk of crushing due to mechanically moving parts.
▶Switchosupplyvoltage.
▶DeviceswithSAFEPOSenergy-pack:CompletelydrainSAFE-

NOTE!
Damage to the seat seal and seat contour when valve is
closed.
Ifthevalveisclosedwhentheactuatorisrotated,theseatseal
andtheseatcontourmaybedamaged.
•Ifthevalveisclosed:Beforerotatingtheactuator,openthe
valveusingthemechanicalmanualcontrol.Fordescription
see“12.2Actuatingvalvemechanically”.

→Placeanopen-endwrench(widthacrossatsM41)onthe
hexagonoftheactuator.
WARNING
If incorrect direction of rotation, risk of injury due to dis-
charge of medium and pressure release.
Ifthedirectionofrotationiswrong,thebodyconnectionmay
becomedetached.
▶Rotateactuatorintheindicateddirectiononly(see“Fig.10:
