6 STRUCTURE AND FUNCTION
6.1 Structure
Theglobevalveconsistsofapneumaticallyactuatedpiston
actuator and a 2/2-way valve body.
Theactuatorismanufacturedfrompolyphenylenesulphide
(PPS).Thetriedandtested,self-adjustingpackingglandensures
hightightness.Theow-enhancingvalvebodymadeofstainless
steelenableshighowvalues.

6.2 Function
Dependingontheversion,theseatofthevalveisclosedwithor
againstthemediumow.
Springforce(CFA)orpneumaticpilotpressure(CFBandCFI)
generatestheclosingforceontheswivelplate.Theforceis
transferredviaaspindlewhichisconnectedtotheactuator
piston.

contributestotheopeningofthevalve.
WARNING!
Medium may be discharged if minimum pilot pressure is too
low or medium pressure too high!
IftheminimumpilotpressureistoolowforCFBandCFIorthe

8.1 Safety instructions
DANGER!
Risk of injury from high pressure and leaking medium!
▶Beforelooseningthelinesandvalves,turnothepressure
andventthelines.
WARNING!
Risk of injury from improper installation!
▶Installationmaybecarriedoutbyauthorizedtechnicians
onlyandwiththeappropriatetools!
Risk of injury from unintentional activation of the system and
an uncontrolled restart!
▶Securesystemfromunintentionalactivation.
▶Followinginstallation,ensureacontrolledrestart.
For control function I – Danger if pilot pressure fails!
ForcontrolfunctionIcontrolandresettingoccurpneumati-
cally.Ifthepressurefails,nodenedpositionisreached.
▶Toensureacontrolledrestart,rstpressurizethedevicewith
pilotpressure,thenswitchonthemedium.
Risk of injury from moving parts in the device!

theaidofasecondpersonandusingsuitableauxiliary
equipment.
▶Use appropriate tools.
8.2 Before installation
•Theglobevalvecanbeinstalledinanyinstallationposition,
preferablywiththeactuatorfaceup.
•Beforeconnectingthevalve,ensurethelinesareush.
•Observedirectionofow(seetypelabel).
8.2.1 Preparatory work
→Cleanpipelines(sealingmaterial,swarf,etc.).
8.2.2 Remove the actuator from the valve body
Only devices with welded body
NOTE!
For valves with installed control:
Whenweldingthevalvebodyintothepipeline,thecontrol
must not be installed.
▶Removecontrolfromtheactuator(seeinstallationchapterin
theoperatinginstructionsforthecorrespondingcontrol).
→Clampthevalvebodyinaholdingdevice.
NOTE!
Damage to the seat seal or the seat contour!
▶Whenremovingtheactuator,ensurethatthevalveisinopen
position.
→ControlfunctionApressurizethepilotairport1withcom-
