- 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 .
