Low-Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to perform reliably and ensure 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 including:
Blending
Crude desalting
Gas crops
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 services similar 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 functions with risky air pollution and dangerous fluids. The Durco G4XZ valve design has undergone rigorous testing and is certified to the most stringent business standards, including 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 via its fire-safe design and building that complies with API 607 seventh edition 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 doesn’t require lubrication for sealing. Instead, เกจวัดแรงดันไฮดรอลิค can merely be adjusted additional into the sleeve to enhance sealing functionality.
Simplified, in-line maintenance
Design features an unbiased plug, packing and high cap seal that enable simple adjustment or re-energization of seals as needed.
