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
theportconnection.
5.2 Properties
•Highsealtightnessduetoself-adjustingpackingglands
(spindlesealelement).
•Highseattightnessduetoswivelplate.
•Actuator can be seamlessly rotated by 360°.
•Maintenance-freeundernormalconditions.
5.2.1 Options
•Control unit
Dependingontherequirements,variouscontrolunitvariants

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.

pressure(controlfunctionBorI,CFBorCFI).
Asthemediumispresentundertheswivelplate,themedium
pressurecontributestotheopeningofthevalve.
WARNING!
Valve leak if there is too little minimum pilot pressure or high
medium pressure!
MinimumpilotpressureforCFBandCFIthatistoolow,or
failingtomeetthepermittedmediumpressure,cancausea
