Hy-Lok Cryogenic Valve Construction

  • Constructed from austenite stainless steel, our cryogenic valves are ideally suited to handle a wide variety of cryogens including LNG, oxygen, ammonia, LPG, methane, and hydrogen.
  • The extreme corrosion-resistance qualities of our valves ensure exceptional performance even in the harshest of atmospheres, like marine environments.
  • Hy-Lok’s cryogenic valves feature a top-entry, bolted bonnet design for easy in-line maintenance. Valves are pressure rated to 750 psi (52 bar) at 100°F, with a temperature rating of -320°F to 700°F (-196°C to 371°C).
  • Designed with the packing below the thread line ensures a long lifecycle for these valves, which also feature anti-blowout proof stems. The one-piece stem is nonrotating. Open/close position is easily indicated as the dust cap functions as a position indicator.
  • Available end connections include screwed, flanged and butt-welds. Reduced and full-bore options are available from 1/2″ to 1 1/2″.
  • Our high-performance valves are fire-safe and designed to BS 6755 Part 2 standards and ratings. They are ideal for LNG, LPG, nitrogen, and cryogenic applications.
