  1. Features & Applications
  • Key Features:
    • Cryogenic Service Capability: Designed for temperatures as low as -196°C (-320°F), suitable for LNG and other liquefied gases.
    • Extended Bonnet: Protects the stem seals and packing from the extreme cold, ensuring operability and preventing ice formation.
    • PCTFE (KEL-F®) Seats: Provides reliable sealing at cryogenic temperatures with excellent dimensional stability.
    • Cavity Pressure Relief: Self-relieving seat design prevents dangerous over-pressure in the ball cavity due to vaporization of trapped cryogenic liquid.
    • Blow-out Proof Stem: Ensures stem retention under all pressure conditions.
    • Anti-Static Device: Dissipates static charge generated by ball/seat friction, critical for flammable media like LNG.
    • Fire-Safe Design: Optional API 607 certification ensures sealing integrity in case of fire.
    • Forged Body: Provides superior strength and reliability at high pressures and low temperatures.
  • Main Applications:
    • LNG (Liquefied Natural Gas): Liquefaction, storage, transportation, and regasification plants.
    • Air Separation Units (ASU): Handling LOX (Liquid Oxygen), LIN (Liquid Nitrogen), LAr (Liquid Argon).
    • Petrochemical: Handling ethylene, methane, and other cryogenic hydrocarbons.
    • Industrial Gas: Cryogenic storage tanks and transfer lines.
