As leading cryogenic ball valve manufacturers, we specialize in crafting valves engineered for extreme temperature challenges, particularly in LNG export facilities. Our renowned “floating trunnion-supported” ball valve, alongside our widely requested side entry ball valves, are meticulously designed to operate efficiently at temperatures ranging from -50°C to -196°C. These valves are crucial in ensuring the safe isolation of LNG lines, effectively preventing leaks, and maintaining the integrity of cryogenic infrastructure. Our unique symmetrical component design allows uniform expansion and contraction, while live-loaded seals accommodate intense dimensional changes, ensuring secure closure tightness. Trust our expertise to meet the rigorous demands of your gas processing and blowdown systems with precision-engineered solutions that withstand even the harshest cryogenic conditions.
A company producing and processing natural gas in North Africa’s punishing conditions required a set of carefully designed and fully tested valves to give consistent shut-off results when operating at -150°F in a fractionating plant.
Specially engineered Cornerstone valves were created and rigorously tested by an independent valve testing company. The customer’s engineer witnessed the full valve testing sequences in a submerged liquid nitrogen bath. The 6″ valves were the tightest the facility had ever tested in their many years of performing cryogenic tests.
Today in North Africa, Cornerstone valves perform as flawlessly as in the lab.
