High-Quality Low-Temperature Cryogenic Metal Side-Entry Floating Ball Valve

I. Core Attributes: Professional-Grade Parameters for Cryogenic Scenarios

• Diameter Range: DN50~DN250 (2″~10″), suitable for medium-small cryogenic pipeline systems.
• Pressure Classes: Class 150~Class 300 (PN20~PN50), with a maximum pressure rating of 5.0MPa, compliant with ASME B16.34 standards.

• Body Material: Valve body and ball made of WCB cast steel or 304 stainless steel, tested for low-temperature impact at -196°C (Charpy impact energy ≥27J) with excellent resistance to cold brittleness. Extended bonnet (150~200mm longer) is standard for cryogenic applications to prevent packing from hardening and leaking at low temperatures.
• Sealing System:
  • Seat: PTFE soft seal (-100°C~150°C) with leakage rate ≤0.5cc/min; metal hard seal (Stellite alloy) for particle-containing media, meeting API 6D Class VI bubble-tight standards.
  • Fire Safety Design: Complies with API 607 standards, equipped with graphite emergency sealing layer for automatic metal-to-metal sealing if soft seal fails.

• Actuation: Manual operation with handwheel locking device, operating torque ≤150N·m for easy operation in low-temperature environments.
• End Connections: Flanged (RF face/RTJ ring joint), compliant with ASME B16.5; socket weld available for DN50~DN200.

• Cryogenic Certifications: ATEX low-temperature explosion-proof certification (-196°C), DNV GL marine certification, suitable for LNG ships, cryogenic chemical plants, etc.
• Customization Services: OEM/ODM options include nickel plating (25μm thickness), explosion-proof electric actuator integration (response time ≤3 seconds).
