Valve settings for the hydrogen filling line
Thread Content
Dear marine industry professionals, have you ever worked on the process system design for hydrogen filling stations? I have a few questions: 1. Are all the valves in the hydrogen filling line manual valves? Are automatic valves necessary, and is it possible to automate the entire filling process? How to achieve it? 2. How can the filling hose ensure that no air gets mixed in when it is removed from the hydrogen cylinder? Is there a check valve or some other device at the end of the hose? 3. Is it necessary to turn off the hydrogen compressor every time filling is completed, to release the hydrogen in the filling line? Should the release valve be set as a manual valve? If set as an automatic valve, should it be a shut-off valve that opens quickly or one that opens slowly? Thank you, please give me some advice. Are there any manufacturers that sell automated filling lines directly? Please give some guidance.
