8. 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 .

  • Extended Bonnet: Protects the stem seals and packing from extreme cold, ensuring operability and preventing ice formation .

  • Forged Body Construction: Provides superior strength and reliability at high pressures (2500LB) and low temperatures .

  • Excellent Throttling Capability: Globe valve design provides precise flow control and regulation.

  • OS&Y Design: Provides visual indication of valve position and prevents stem thread exposure to media .

  • Backseat Design: Protects packing from system pressure when valve is fully open.

  • BS 6364 Certification: Designed and tested to international cryogenic valve standard .

  • Low Fugitive Emissions: Optional ISO 15848-1 certification for environmental compliance .

• 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 .

  • Refinery: High-pressure cryogenic applications .
