RANGER’s Cryogenic Top Entry Ball Valves for LNG service are engineered, high-performance valves, that leverage CNC machining equipment, as well as other specialty equipment, and dust-free assembly areas to ensure a consistent and high-quality product.

Key Application(s)

  • Liquefied natural gas (LNG)

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
  • Fire-safe, antistatic design
  • Drop plate design
  • Extended bonnet design with stable sealing
    • RANGER’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 vapor and not to the cold liquid.
