The G4XZ valve can be used in hydrofluoric acid (HF) alkylation trade processes together with:
Blending
Crude desalting
Gas vegetation
Isomerization
Light ends
Sulphur crops
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve additionally can be used for deadly, toxic and sub-zero fluid services similar to chlorine, anhydrous hydrogen chloride, phosgene, propylene oxide, isobutane and HF acid.
