Low-Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to carry out reliably and ensure compliance with the most stringent ISO and API fugitive emissions standards, together with ISO 15848-1-BH-CO3 and API 641 1st version. pressure gauge can be used in hydrofluoric acid (HF) alkylation trade processes including:
Blending
Crude desalting
Gas crops
Isomerization
Light ends
Sulphur plants
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve additionally can be used for lethal, poisonous and sub-zero fluid services corresponding 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 purposes with volatile air pollution and unsafe fluids. The Durco G4XZ valve design has undergone rigorous testing and is certified to probably the most stringent business standards, together with ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st version.
Engineered for safety
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 standards (for exterior leakage only).
Improved reliability and uptime
The tight shut-off efficiency is repeatable and reliable to minimize unforeseen downtime; The G4XZ valve design does not require lubrication for sealing. Instead, the plug can merely be adjusted additional into the sleeve to improve sealing capability.
Simplified, in-line maintenance
Design options an unbiased plug, packing and top cap seal that enable easy adjustment or re-energization of seals as needed.
