Fields of application :
Flow control of corrosive, hazardous and ultrapure process fluids and gases.
For media where stainless steel and exotic alloys do not provide sufficient corrosion resistance
As an economic alternative to exotic alloy valves
For metal-reactive media, e.g. H2O2
For biotechnology and high-purity media where excellent cleaning
and anti-adhesive surfaces are important
For highly permeating media
