CRYO-SEAL™ Ultra-Low Temperature Socket-Weld Ball Valves
API 607 Fire-Safe Certified | -196°C Cryogenic Fluid Control | 150LB-1500LB Pressure Range
Core Technology Advantages
✅ Zero-Leak Cryogenic Sealing
Precision-engineered dual-bevel metal seats maintain airtight performance across -196°C to 200°C thermal cycles, outperforming standard PTFE-seated valves by 3x lifespan in LNG/LPG applications.
✅ Fire-Safe API 607 Compliance
Patented trunnion-assisted metal-to-metal secondary seal activates automatically at 650°F, achieving 0% leakage in BS 6755 fire endurance tests – critical for petrochemical safety compliance.
✅ Frictionless High-Pressure Control
Computer-optimized ball geometry reduces operating torque by 40% vs. traditional designs (ASME B16.34 verified), enabling smooth actuation even at 1500LB working pressures.
