  1. Features & Applications
  • Key Features:
    • Cryogenic Service Capability: Designed for temperatures as low as -196°C (-320°F) , suitable for LNG, LOX, LIN, and other liquefied gases .
    • 3-Way Configuration: T-port or L-port design allows for mixing, diverting, or switching flow in cryogenic systems.
    • Extended Bonnet: Protects the stem seals and packing from extreme cold, ensuring operability and preventing ice formation .
    • No-Trap Cavity Design: Relief hole in ball or self-relieving seats prevents dangerous pressure buildup in the ball cavity due to vaporization of trapped cryogenic liquid .
    • Efficient Heat Transfer: Narrow clearance between stem and bonnet extension maintains stem seals at near-ambient temperature .
    • 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 607/6FA certification ensures sealing integrity in case of fire .
    • BS 6364 Certification: Designed and tested to international cryogenic valve standard .
    • Flexible Bonnet Installation: Bonnet can be installed at up to 45° angle for piping flexibility .
  • 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, LPG, and other cryogenic hydrocarbons .
    • Industrial Gas: Cryogenic storage tanks and transfer lines.
    • Refrigeration Systems: Low-temperature industrial refrigeration.

*Disclaimer: The above data is prepared based on common industry standards (API 6D, ASME B16.34, BS 6364) for cryogenic 3-way ball valves . Specific dimensions, materials, and pressure ratings may vary by manufacturer. For cryogenic service (below -46°C), valves must be tested per BS 6364 at -196°C. The final technical agreement and certified drawings shall prevail.
