Reliable Cryogenic Performance
Engineered for extreme low-temperature service down to -196°C, ensuring stable operation in LNG, LPG, LOX and other liquefied gas systems.
Extended Bonnet Design
Reduces heat transfer to the sealing system, protecting stem packing and ensuring safe, long-term cryogenic operation.
Bubble-Tight Shut-Off
Precision-machined ball and high-performance seats provide zero-leakage sealing under both high pressure and ultra-low temperature conditions.
Low Operating Torque
Optimized ball-seat contact reduces friction, enabling smooth quarter-turn operation even after thermal cycling.
Durable Low-Temperature Materials
Selected carbon steel and stainless steel materials maintain toughness and impact resistance in cryogenic environments.
High Reliability in Critical Service
Widely used in LNG terminals, storage tanks, transport pipelines, and industrial gas processing systems where failure is not an option.
