Low-Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to perform 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 edition. The G4XZ valve can be utilized in hydrofluoric acid (HF) alkylation industry processes together with:
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve also can be utilized for lethal, poisonous and sub-zero fluid services 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 purposes with risky air pollutants and hazardous fluids. The Durco G4XZ valve design has undergone rigorous testing and is certified to the most stringent industry standards, including 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 by way of its fire-safe design and development that complies with API 607 7th version and ISO 10497 2010 fire-safe standards (for external leakage only).
Improved reliability and uptime
The tight shut-off performance is repeatable and reliable to attenuate unexpected downtime; The G4XZ valve design doesn’t require lubrication for sealing. Instead, เกจวัดแรงดันแก๊สหุงต้ม can simply be adjusted further into the sleeve to enhance sealing capability.
Simplified, in-line maintenance
Design features an impartial plug, packing and high cap seal that enable easy adjustment or re-energization of seals as needed.
