What valves are used at the inlet and outlet of the new hydrogen hydrogenation unit and the recycled hydrogen compressor?
Thread Content
With a design pressure of 12 MPa, what type of valves should be used at the inlet and outlet of the hydrogenation fresh hydrogen machine and the recycle hydrogen compressor – ball valves or gate valves? Which brand is suitable for these valves, and should they be imported or domestically produced?
Our inlets and outlets are either ball valves on tracks or a combination of ball valves on tracks and gate valves; in both cases, it is a dual-valve system.
The inlet and outlet of the new hydrogen compressor seem to be double ball valves, while those of the circulation pump are electric valves (with interlock)
The inlet and outlet of the conventional hydrogenation cycle machine are equipped with electric valves, along with interlocks； The inlet and outlet of the new hydrogen compressor for liquid-phase diesel hydrogenation are electric valves and gate valves ； Both the old conventional hydrogenation units with fresh hydrogen and the circulators use double gate valves
