| Abstract: | Several different valve needles were designed and manufactured for a superfluid helium system. The numerical simulation was used to analyze the flow characteristics of cryogenic throttle valves. A test bench was also built up to investigate the performance of the different valve needles. Finally, an appropriate throttle valve was chose to serve the superfluid helium system. |

| Keywords: | cryogenic throttle valve valve needle flow coefficient |
