Light ends
Sulphur vegetation
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve additionally can be utilized for deadly, poisonous and sub-zero fluid companies 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 applications with risky air pollution and hazardous fluids. The Durco G4XZ valve design has undergone rigorous testing and is certified to probably the most stringent trade standards, including ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st version.
Engineered for security
The G4XZ valve ensures increased plant and personnel security through its fire-safe design and building that complies with API 607 seventh edition and ISO 10497 2010 fire-safe standards (for external leakage only).
Improved reliability and uptime
The tight shut-off efficiency is repeatable and reliable to reduce unforeseen downtime; The G4XZ valve design does not require lubrication for sealing. Instead, the plug can merely be adjusted further into the sleeve to improve sealing functionality.
Simplified, in-line upkeep
Design options an independent plug, packing and top cap seal that enable easy adjustment or re-energization of seals as needed.
