Low-Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to perform reliably and guarantee compliance with the most stringent ISO and API fugitive emissions standards, 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 vegetation
Isomerization
Light ends
Sulphur plants
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve also can be used for lethal, poisonous and sub-zero fluid companies 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 unstable air pollutants and unsafe fluids. The Durco G4XZ valve design has undergone rigorous testing and is licensed to probably the most stringent industry standards, including ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st edition.

The G4XZ valve ensures increased plant and personnel security via its fire-safe design and building that complies with API 607 7th version and ISO 10497 2010 fire-safe standards (for exterior leakage only).
Improved reliability and uptime
The tight shut-off efficiency is repeatable and reliable to attenuate unforeseen downtime; The G4XZ valve design does not require lubrication for sealing. Instead, the plug can simply be adjusted additional into the sleeve to improve sealing capability.
Simplified, in-line upkeep
Design features an independent plug, packing and top cap seal that permit easy adjustment or re-energization of seals as wanted.
