voids thewarranty.
Techtip
Our life tests indicate that
thesevalveswill typically
givemore than100,000
cyclesbefore requiring
any service. Thisassumes
that thefluidused is
freeofparticulatesand
not reactive toward the
valvecomponents. If
the streammaycontain
particulates,or if ithas
high salt contentwhich
couldprecipitatewithin
the sample lines,usean
in-linefilter.
Note: Valveswithpurge
portsareavailableon
request.

C20Zvalveswithzerodeadvolume
fittings (10-32 thread) are shippedwith

maybeordered separately. Standard
specificationsare100psi gas/250psi
liquidat75°C. On request, thepressure

The ModelC22Z isaconventional two
position sample injector and switching
valve,with4,6,8,or 10ports. Sample
injection requiresa loop,ordered
separately.
The ModelC24Z isan internal sample
injector, for applications inwhich the
sample size is smaller than thatof any
availableexternal loop. Sample sizes
availableare0.2,0.5,and1µl.
WithCheminert1/4-28
Fittings
C20Seriesvalvecapshave female
threads fordirect connectionof lines–
nocouplingsare required. C20Series
valvesareavailable in4,6,8,and10
port versions. Standard specifications
are100psi gas/250psi liquidat 75°C.
MulticoloredCheminert 1/4-28flange-
lessfittings for 1/16"or 1/8"OD tubing
(dependingon thevalvemodel) are
included.
ModelC22 valvesareused for sample
injectionor switching. (Functionally
equivalent toModel C22Z) Sample
injection requiresa loop,ordered
separately.
The ModelC24 isan internal sample
injector like theC24Z,availablewith
0.5,1.0,or 2.0µl sample size.
