Low-Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to perform reliably and guarantee compliance with probably 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 including:
Blending
Crude desalting
Gas vegetation
Isomerization
Light ends
Sulphur vegetation
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve additionally can be utilized for lethal, toxic and sub-zero fluid companies corresponding to 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 purposes 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, including ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st version.
เกจวัดแรงดัน for security
The G4XZ valve ensures elevated plant and personnel security via its fire-safe design and building that complies with API 607 7th version and ISO 10497 2010 fire-safe requirements (for exterior leakage only).
Improved digital pressure gauge and uptime
The tight shut-off performance is repeatable and reliable to attenuate unexpected downtime; The G4XZ valve design does not 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 independent plug, packing and top cap seal that enable easy adjustment or re-energization of seals as wanted.
