Magnetically levitated centrifugal air conditioning are increasingly being applied in large-scale construction and data centers, offering high efficiency, eliminating the need for lubricating oil in compressors, and making maintenance easier. However, they also pose challenges for valve components, as many precision automatic valves used to rely on lubrication from the system's oil. We have developed numerous self-lubricating components that no longer depend on system lubrication, mainly through innovative materials.
