AI Technical Summary
Technical Problem
Ball valves experience leakage at cryogenic temperatures due to shrinkage or deformation of seat inserts and other components, leading to fluid loss.
Method used
A ball valve design featuring a seat insert with angled walls and a spring mechanism that biases the insert against the angled wall, enhancing sealing forces to prevent leakage through multiple paths, even under cryogenic conditions.
Benefits of technology
The angled wall and spring mechanism significantly increase sealing force, reducing leakage by at least 1% to 150% under cryogenic conditions, ensuring a fluid-tight seal.
