What is the purpose of pneumatic ball valve on maglev train
As a new type of non air contact vehicle, the maglev train has the advantages of ultra-high speed, low noise, energy saving and so on, and has been paid more and more attention. Of course, the application of pneumatic ball valve pneumatic ball valve is a very key technology. In the 1980s, the maglev train technology in Japan, Germany and other countries had reached the applicable level.
