Selection of hydrogen pipeline valves
Thread Content
Ball valves or globe valves are recommended for the valves on the inlet and outlet pipelines of the cyclohydrogen compressor. Which model is commonly used for ball valves?
Only new hydrogen compressors use ball valves (ball valves with tracks), while for circulating hydrogen compressors, the valves used in the projects we have worked on are gate valves; except in the Chevron process package (where basically ball valves with tracks are used on all hydrogen pipelines)
For hydrogen compressor ball valves, full-bore metal hard-sealed ball valves can be used; all components must be degreased to remove oil, but the choice of valve also depends on the temperature of the hydrogen gas in the pipeline. In some operating conditions, dust may be present. So globe valves and track ball valves are also an option.
