TECHNICAL DATA SHEET

Product Name: 2-inch 900LB 2-Piece Cryogenic Floating Ball Valve
Model/Specification: 2″-900LB-CRYO-2PC-RTJ
Valve Type: 2-Piece Floating Ball Valve (Cryogenic Service)
Connection Type: RTJ Flanged (Ring Type Joint) – ASME B16.5
Body Material: Stainless Steel – ASTM A182 F316

1. Basic Design Parameters

2. Technical Specifications

3. Material of Construction (F316 Stainless Steel)

4. Main Dimensions & Connection Details

Note: Dimensions for 2″ Class 900 RTJ Flanged Cryogenic Ball Valve. Based on ASME B16.10, API 6D, and industry standards for cryogenic extended bonnet.

4.1 End-to-End Dimensions (Face-to-Face – RTJ)

Note: Height (H) includes extended bonnet for cryogenic service. Weight depends on actuator/gearbox choice.

4.2 RTJ Flange Details (Per ASME B16.5 – Class 900)

4.3 Extended Bonnet (Cryogenic Feature)

• Extension Length: Designed to keep stem packing above frost line (typically 200-300 mm for 2″ valve at -196°C).
• Drip Plate: Included to prevent ice formation on body/bonnet joint.
• Heat Transfer Design: Narrow clearance between stem and bonnet ID ensures packing near ambient temperature.
• Material: F316 stainless steel (same as body).

5. Pressure-Temperature Rating (ASME B16.34 / Class 900)

*Material Group: Stainless Steel – ASTM A182 F316 with PCTFE/PEEK seats*

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

6. Test Pressure (API 598 / BS 6364)

7. Flow Characteristics (2″ – Full Bore)

8. Features & Applications

• Key Features:
• 2-Piece Forged Body: Allows in-line maintenance of trim while providing robust, leak-free construction.
• 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 stem seals from extreme cold, ensuring operability and preventing ice formation.
• Floating Ball Design: Ball floats against downstream seat, providing tight, bidirectional sealing.
• RTJ Flanged Ends: Metal-to-metal ring joint seal for high-pressure and high-integrity applications.
• No-Trap Cavity Design: Relief hole in ball or self-relieving seats prevents dangerous pressure buildup due to vaporization of trapped cryogenic liquid.
• Anti-Static Device: Dissipates static charge, critical for flammable media like LNG.
• Blow-out Proof Stem: Retained within body even if gland is removed.
• Fire-Safe Design: Optional API 607 certification ensures sealing integrity in case of fire.
• BS 6364 Certification: Designed and tested to international cryogenic valve standard.
• NACE MR0175 Compliance: Optional for sour service (H₂S) environments.
• Lockable Handle / Gear: Safety lockout capability for maintenance.
• Main Applications:
• LNG (Liquefied Natural Gas): Liquefaction, storage, transportation, and regasification plants.
• Air Separation Units (ASU): Handling LOX, LIN, LAr.
• Petrochemical: Ethylene, propylene, LPG, and other cryogenic hydrocarbons.
• Industrial Gas: Cryogenic storage tanks and transfer lines.
• Refrigeration Systems: Low-temperature industrial refrigeration.
• High-Pressure Cryogenic Systems: Class 900 applications.

9. Comparison: 2-Piece vs. 3-Piece Design

*For cryogenic service, 2-piece design offers reliable performance with fewer potential leak paths.*
