ispossibleonlyincombinationwithacontrolunit.
Possiblecontrolunitsare:
PositionerType8692,8694and8696

6.1 Structure
Theangle-seatcontrolvalveconsistsofapneumatically
operatedpistonactuator,acontrolconeanda2/2-wayangle-
seatbody.
Viaadowelpin,thecontrolconeismodularlycoupledtothe
actuatorspindleforquickchangeovers.
Forthebody,almostanylineconnectionsarepossible.
Athreadedportandaweldedendareoeredasastandard
version.
Thevalveseatsareincorporateddirectly.Theowinletisalways
underseat.

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
permittedmediumpressureisexceeded,leaksmayoccur.
