Low-Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to carry out reliably and guarantee compliance with essentially the most stringent ISO and API fugitive emissions requirements, including ISO 15848-1-BH-CO3 and API 641 1st version. The G4XZ valve can be used in hydrofluoric acid (HF) alkylation business processes including:
Blending
Crude desalting
Gas vegetation
Isomerization
Light ends
Sulphur vegetation
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve also can be used for lethal, poisonous 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. The Durco G4XZ valve design has undergone rigorous testing and is certified to probably the most stringent industry standards, including ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st edition.
เกจ์วัดแรงดันลม for safety
The G4XZ valve ensures elevated plant and personnel safety by way of its fire-safe design and development that complies with API 607 seventh 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 reduce unexpected downtime; The G4XZ valve design doesn’t require lubrication for sealing. Instead, the plug can merely be adjusted additional into the sleeve to enhance sealing functionality.
Simplified, in-line maintenance
Design options an independent plug, packing and high cap seal that enable simple adjustment or re-energization of seals as needed.
