Abstract: Sticking and jamming of the kinematic valve pair is one of the most common failure modes for liquid hydrogen and liquid oxygen rocket engine valves. Therefore, the prevention of sticking and jamming is one of the most important issues in the reliability design of valves. As the sticking and jamming usually occurs after a certain period of a valve's operation, usually it will not be discovered before its subsequent failure. Therefore, the sticking and jamming becomes a major threat to the valve reliability, especially, in low temperature conditions. This paper reviews the valve sticking and jamming cases both at home and abroad, the failure mechanism, the reliability design criterion, and the precautionary measures in practical cases, to serves as a reference for designers of spacecraft motors and low-temperature valves.
