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 requirements, including ISO 15848-1-BH-CO3 and API 641 1st edition. The G4XZ valve can be used in hydrofluoric acid (HF) alkylation trade processes together with:
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve additionally can be used for deadly, toxic and sub-zero fluid services similar to chlorine, anhydrous hydrogen chloride, phosgene, propylene oxide, isobutane and HF acid.
Reduced fugitive emissions
Operators can set up the Durco G4XZ valve with confidence in functions with risky air pollution and hazardous fluids. เกจ์ลมsumo has undergone rigorous testing and is certified to the most stringent trade standards, together with 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 through its fire-safe design and construction that complies with API 607 7th edition and ISO 10497 2010 fire-safe requirements (for exterior leakage only).
Improved reliability and uptime
