Flowserve’s Durco® G4XZ

Low-Emission Plug Valve

Flowserve engineered the Durco® G4XZ low-emission plug valve to carry out reliably and guarantee compliance with essentially the most stringent ISO and API fugitive emissions requirements, including ISO 15848-1-BH-CO3 and API 641 1st version. The G4XZ valve can be utilized in hydrofluoric acid (HF) alkylation trade processes including:
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 deadly, poisonous and sub-zero fluid providers such as chlorine, anhydrous hydrogen chloride, phosgene, propylene oxide, isobutane and HF acid.
Reduced pressure gauge 10 bar can set up the Durco G4XZ valve with confidence in purposes with volatile air pollutants and dangerous fluids. The Durco G4XZ valve design has undergone rigorous testing and is certified to the most stringent trade standards, including ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st version.
Engineered for safety

The G4XZ valve ensures elevated plant and personnel safety through its fire-safe design and building that complies with API 607 seventh version and ISO 10497 2010 fire-safe requirements (for exterior leakage only).
Improved reliability and uptime

The tight shut-off performance is repeatable and reliable to minimize unexpected downtime; The G4XZ valve design doesn’t require lubrication for sealing. Instead, the plug can merely be adjusted additional into the sleeve to enhance sealing functionality.
Simplified, in- ไดอะแฟรม , packing and high cap seal that allow simple adjustment or re-energization of seals as needed.
