5.1 General description
The2/2-wayglobevalveType2101issuitableforliquidandgaseous
media.Usingneutralgasesorair(controlmedia),it controlsthe
owofwater,alcohol,oil,fuel,hydraulicuid,salinesolution,lye,
organicsolventsandvapour(owmedia).
Onespecial characteristic of theglobe valvesis the screwed-in
seats,whichcanbeusedtoreducetheseatsize,inparticularfor
thecontrolvalve(Type2301).
Denition DN
DNreferstothenominaldiameteroftheseat,notthatof

6 STRUCTURE AND FUNCTION
6.1 Structure
Theglobevalveconsistsofapneumaticallyactuatedpiston
actuator and a 2-way body.
Theactuatorismadefrompolyphenylenesulphide(PPS).The
proven,self-adjustingpackingglandguaranteesahighdegreeof
tightness.Thestainlesssteelvalvebodyaidsinowandfacili-
tateshighowrates.

8.1 Safety instructions
DANGER!
Risk of injury due to high pressure and escaping medium.
▶Beforeworkingonthedeviceorsystem,switchothepres-
sure.Ventoremptythelines.
WARNING!
Risk of injury due to improper assembly!
▶Onlytrainedtechniciansmayperforminstallationwork.
▶Performinstallationsusingsuitabletoolsonly.
Risk of injury due to unintentional activation of the system
and uncontrolled restart.
▶Secureequipmentagainstunintentionalactivation.
▶Ensurethatthesystemstartsupinacontrolledmanneronly.
For control function I – risk of pilot pressure failure.
The valve stays in an undened position in the event of a pilot
pressurefailure.
▶Toensureacontrolledrestartofthedevice,applypilotpressure
andactivatethemedium.
Risk of injury due to moving parts.
▶Donotreachintoopeningsinthedevice.

Installation
CAUTION!
Risk of injury due to heavy device.
Duringtransportationorinstallationwork,aheavydevicemay
falldownandcauseinjuries.
▶Transport,installandremoveheavydevicewiththeaidofa
second person only.
▶Use suitable tools.
8.2 Before installation
•Anyinstallationpositionoftheglobevalveispossible,prefe-
rablywiththeactuatorfacingupward.
•Ensurethatpipelinesarealignedbeforeconnectingthevalve.
•Noteowdirection(seetypelabel).
8.2.1 Preparatory work
→Clearimpuritiesfrompipelines(sealmaterial,metalchips,
etc.).
8.2.2 Removing actuator from the valve body
For devices with welded connection
NOTE!
For valves with a mounted control unit:
Whenweldingthevalvebodyintothepipeline,thecontrolunit
must not be installed.
▶Uninstallthecontrolunitfromtheactuator(seechapteron
installationintheoperatinginstructionsofthecorresponding
controlunit).
→Clamp valve body into a collet.
NOTE!
Damage to the seat seal or seat contour!
▶Whenremovingtheactuator,thevalvemustbeintheopen
position.
→ForcontrolfunctionApressurisethepilotairport1withcom-
pressedair(5bar):Valveopens.
→Place a suitable open-end wrench on the wrench at of the
nipple.
→Unscrewactuatorfromthevalvebody.
For other device variants:
→Onlyuninstalltheactuatorifrequiredbythecustomer.

WARNING!
Risk of injury due to improper installation!
Failuretoobservethetighteningtorquevalueisdangerousdue
totheriskofdamagetothedevice.
▶Useanopen-endwrenchforinstallation,neverapipe
wrench.
▶Observetighteningtorque(see„Tab.8:Tighteningtorques
valvebody/nipple“).
Dirt trap for devices with approval according to DINEN161
AccordingtoDINEN161"Automaticshut-ovalvesforgas
burnersandgasappliances",adirttrapmustbeinstalled
upstreamofthevalve.Thedirttrapmustpreventthepenetration
ofa1mmtestpin.
→Iftheapprovalalsoappliestothestainlesssteelvalvebody,
suchadirttrapmustbeattachedinfrontoftheglobevalve.
8.3.1 Installing the body
Welded connection
→Weld or bond valve body in pipeline system.
Other body variants
→Connect valve body to pipeline.

riskofexplosioninoxygenapplications!
▶Forspecicapplications,e.g.oxygenoranalysisapplica-
tions,useapprovedlubricantsonly.
→Beforere-installation,greasenipplethreadoftheactuator
(e.g.usingKlüberpasteUH196-402fromKlüber).
NOTE!
