← TechnologyWhich risk increases when an oxygen process control valve stiction occurs during liquid oxygen (LOX) transfer?
A)Cryopump thermal oscillations
B)Rapid over-pressurization events✓
C)Catalytic flow conversion stalls
D)Inertial induced manifold collapse
💡 Explanation
A process control valve stiction directly hinders accurate flow metering; therefore, it prevents required fine adjustments, causing rapid pressure build-up. Rather than oscillations or collapse, oxygen's pressure amplifies quickly and dangerously because oxygen flow is uncontrolled upstream of a restriction.
