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 standards, including ISO 15848-1-BH-CO3 and API 641 1st version. The G4XZ valve can be used in hydrofluoric acid (HF) alkylation industry processes together with:
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve additionally can be used for lethal, toxic and sub-zero fluid providers similar 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 functions with volatile air pollution and unsafe fluids. The Durco G4XZ valve design has undergone rigorous testing and is licensed to the most stringent industry requirements, together with ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st edition.
Engineered for safety
The G4XZ valve ensures increased plant and personnel security through its fire-safe design and construction that complies with API 607 seventh edition and ISO 10497 2010 fire-safe requirements (for exterior leakage only).
Improved เกจวัดแรงดันน้ําไทวัสดุ 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 further into the sleeve to enhance sealing capability.
Simplified, in-line maintenance
Design features an unbiased plug, packing and top cap seal that allow easy adjustment or re-energization of seals as needed.
