Low-Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to perform reliably and guarantee compliance with essentially the most stringent ISO and API fugitive emissions standards, together with ISO 15848-1-BH-CO3 and API 641 1st version. The G4XZ valve can be utilized in hydrofluoric acid (HF) alkylation trade processes together with:
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 corresponding to chlorine, anhydrous hydrogen chloride, phosgene, propylene oxide, isobutane and HF acid.
Reduced fugitive emissions
Operators can install the Durco G4XZ valve with confidence in purposes with risky air pollutants and dangerous 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 edition.
Engineered for security
The G4XZ valve ensures elevated plant and personnel security through its fire-safe design and construction that complies with API 607 7th version and ISO 10497 2010 fire-safe requirements (for exterior leakage only).
Improved เกจวัดแรงดันsumo and uptime
The tight shut-off performance is repeatable and reliable to attenuate unforeseen downtime; The G4XZ valve design doesn’t require lubrication for sealing. Instead, the plug can merely be adjusted additional into the sleeve to improve sealing capability.
Simplified, in-line maintenance
Design options an unbiased plug, packing and top cap seal that enable easy adjustment or re-energization of seals as wanted.
