LNG Cryogenic Top Entry Ball Valves

FZV’s Cryogenic Top Entry Ball Valves for LNG service have been developed by FZV’s engineering team and through the investment in FZV’s cryogenic laboratory. These engineered, high-performance valves, leverage FZV’s CNC machining equipment, other speciality equipment, and clean assembly areas to ensure a consistent and high-quality product.

Key Application

  • LIQUEFIED NATURAL GAS

Design Features

  • Sizes from NPS 1/2 to NPS 24
  • Class range from 150 to 2500
  • Working temperature: -196℃ to 121℃
  • One piece construction to reduce leakage points
  • Firesafe, antistatic design
  • Drop plate design
  • Extended bonnet design with stable sealing
    • FZV’s cryogenic ball valves bonnet extensions (often specified by the customers for the specific service conditions), provide a sufficient gas column to ensure the seal packing is only exposed to vapour and not to the cold liquid.
