Example:
AnA4C6WE (airactuated1/16"6port
WEvalvewitha4" standoff)madeof
HastelloyC-22wouldbedesignated
A4C6WEHC.
Thecost is$830+$170=$1000.
Due todesign requirements,several
special gradesof stainless steelmay
beusedwhere“HPLCgrade”isnoted.
The specific types includeNitronic
60,Type316 stainless steel,andType
316L stainless steel. VICIwill select
thematerial tobeusedbasedon

The standardvalvebodymaterial isNitronic60, agall-resistant stainless steel
whichhasproven superior toType316or 303 in themajorityof applications.
Valvesmayalsobeordered inHastelloyC-22, Inconel 600,Type316 stainless,
Monel 400,Nickel 200,Nitronic50,orTitanium.
Medium temperatureGCvalves
havea rotormadeofValconE,a
polyaryletherketone/PTFEcomposite.
Thehigh temperatureversionsusea
polyimide/PTFE/carboncomposite
designatedValconT. ValconH,
acarbon-fiber-reinforced,PTFE-
lubricated inertpolymer, is standard
inHPLCvalves.
Appropriatefittingsare suppliedwith
all valves. Valves ratedat 1000psi or
lesshaveType303 stainless ferrules;
those ratedabove1000psi haveType
316 stainless ferrules. Avalveordered
