TheType2301globecontrolvalvecanonlybeusedin
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,
