Low-Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to perform reliably and ensure compliance with 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 utilized in hydrofluoric acid (HF) alkylation business processes together with:
Blending
Crude desalting
Gas plants
Isomerization
Light ends
Sulphur vegetation
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve also can be used for deadly, poisonous and sub-zero fluid providers corresponding 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 purposes with unstable air pollution and hazardous fluids. ตัววัดแรงดันน้ำมัน has undergone rigorous testing and is licensed to essentially the most stringent trade standards, together with ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st edition.
Engineered for security
The G4XZ valve ensures elevated plant and personnel safety by way of its fire-safe design and development that complies with API 607 7th edition and ISO 10497 2010 fire-safe standards (for external leakage only).
Improved reliability and uptime
