Low-Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to carry out reliably and guarantee compliance with the most stringent ISO and API fugitive emissions requirements, including ISO 15848-1-BH-CO3 and API 641 1st edition. The G4XZ valve can be utilized in hydrofluoric acid (HF) alkylation trade processes together with:
Blending
Crude desalting
Gas crops
Isomerization
Light ends
Sulphur plants
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve also can be utilized for lethal, toxic and sub-zero fluid providers such as chlorine, anhydrous hydrogen chloride, phosgene, propylene oxide, isobutane and HF acid.
Reduced fugitive emissions
Operators can install the Durco G4XZ valve with confidence in applications with unstable air pollutants and unsafe fluids. เกจวัดแรงดัน4บาร์ has undergone rigorous testing and is certified to probably the most stringent trade requirements, including ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st version.
Engineered for security
The G4XZ valve ensures increased plant and personnel security via its fire-safe design and building that complies with API 607 seventh edition and ISO 10497 2010 fire-safe standards (for external 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 simply be adjusted further into the sleeve to enhance sealing capability.
Simplified, in-line upkeep
Design features an unbiased plug, packing and high cap seal that allow simple adjustment or re-energization of seals as needed.
