combinationwithacontrolunit.

Possible control units are:

PositionerType8692,8694and8696

ProcesscontrollerType8693

6.1 Structure

Theglobecontrolvalveconsistsofapneumaticallyoperated

pistonactuator,acontrolconeanda2/2-wayglobebody.

Thecontrolconeismodularlyconnectedtotheactuatorspindle

viaaspring-typestraightpin,andcanthusbequicklyreplaced.

Nearly all line connections are possible for the body. Bushing,
