4.3 Extended Bonnet (Cryogenic Feature)

• Extension Length: Designed to keep packing box above frost line (typically 200mm – 300mm for 2″ valve, depending on service temperature [-196°C]) .
• Drip Plate: Included to prevent ice formation on the body/bonnet joint.
• Heat Transfer Design: Narrow space between stem and bonnet ID for efficient heat transfer .

4.4 Port Configuration

Note: Specify required flow pattern when ordering.

5. Pressure-Temperature Rating (ASME B16.34 / Class 300)

*Material Group: Stainless Steel (A182 F304/F316) with PCTFE/PTFE Seats *

*Note: For cryogenic service (below -46°C), valves are tested and certified per BS 6364 at -196°C .*

7. Test Pressure (API 598 / BS 6364)

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 .
• 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.
