GEKO top entry cryogenic ball valve adopts a full-bore design that ensures maximum flow efficiency while maintaining low pressure drop. The PCTFE soft seat and metal seat options (STL / NI55 / TCC) provide excellent sealing integrity under extreme temperatures.

 

The lip-seal design offers both flexible compensation like a spring and excellent tightness similar to PTFE, ensuring zero leakage performance even in cryogenic environments.

 

The extended bonnet with optimized gap control (<1 mm) isolates the packing area from the cryogenic zone, preventing freezing and reducing stem friction. Finite Element Analysis (FEA) determines the ideal bonnet thickness and ARC cooling design, improving cooling efficiency and mechanical stability.

 

The top entry structure allows online maintenance, reducing downtime and simplifying servicing without disassembling the valve from the pipeline.

 

  • Top Entry Design: Enables easy in-line maintenance and quick replacement of internal components.

  • Extended Bonnet: Precisely controlled stem-to-bonnet clearance ensures reliable performance under cryogenic temperatures.

  • Dual Stem Sealing: Lip seal as primary and packing as secondary ensures leak-free operation while reducing packing quantity.

  • Lip-Seal Technology: Combines spring-like flexibility with PTFE-level sealing for superior low-temperature tightness.

  • Drip Plate Design: Increases cooling area and prevents condensate ingress into the valve body, avoiding ice formation.

  • Self-Centering Gland Flange: Prevents stress imbalance, ensuring consistent sealing compression.

  • DIB-2 (Double Isolation and Bleed) Seats: Safely releases cavity pressure, preventing overpressure risk.

  • Low Torque & Anti-Blowout Stem: Ensures smooth operation and enhanced safety under pressure.

  • Fire Safe & Anti-Static: Meets API607 and ISO15848 standards, ensuring safety during emergencies.

  • Cryogenic Precision Machining: Minimizes stem gap (<1 mm) for smooth rotation and prevents freezing-induced damage.

  • Fully Threaded Fasteners: Prevents long-term deformation under cryogenic stress for lasting seal integrity.
