diaphragm seal -Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to perform reliably and ensure compliance with essentially the most stringent ISO and API fugitive emissions standards, together with 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 crops
Isomerization
Light ends
Sulphur vegetation
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve also can be utilized for lethal, poisonous and sub-zero fluid companies 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 dangerous fluids. The Durco G4XZ valve design has undergone rigorous testing and is certified to essentially the most stringent business requirements, including ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st version.
Engineered for safety
The G4XZ valve ensures increased plant and personnel security via its fire-safe design and building 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 does not require lubrication for sealing. Instead, the plug can merely be adjusted additional into the sleeve to enhance sealing capability.
Simplified, in- ไดอะแฟรม features an independent plug, packing and top cap seal that allow easy adjustment or re-energization of seals as wanted.
