Blending
Crude desalting
Gas plants
Isomerization
Light ends
Sulphur vegetation
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve also can be utilized for lethal, poisonous and sub-zero fluid providers such as chlorine, anhydrous hydrogen chloride, phosgene, propylene oxide, isobutane and HF acid.
Reduced fugitive emissions
Operators can set up the Durco G4XZ valve with confidence in functions with risky air pollution and unsafe fluids. The Durco G4XZ valve design has undergone rigorous testing and is licensed to probably the most stringent trade requirements, together with ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st version.
Engineered for safety
