For the flare control valve of this device, should a fine-tuning control valve or a full-open/full-close valve be used?

Hello everyone. I have a question for you: after the overhead flare water seal tank, should a fine-tuning control valve or a on/off control valve be used at the flare control valve?
We usually use ordinary control valves equipped with positioners; on-off valves have too much impact on the system, and there’s no need for them
Generally, larger-scale torch systems are equipped with multiple discharge stages, and the number and level of valves to be opened are determined based on pressure conditions. As for emergency torches, using fine-tuning control valves does not meet safety standards; instead, cut-off valves are used, with an opening response time of no more than 5 seconds

We don’t have any control valves after the water seal tank; it seems like the fine-tuning valve isn’t very useful
There is no control valve behind our water seal tank; when gas escapes through the water seal, it enters the flare
Fully open and fully closed valves should be used to meet the requirements for rapid pressure relief
There is no control valve behind our water seal tank; when gas breaks through the water seal, it enters the flare； Even if adding them, full-open and full-close valves should be used. It’s a lifeline.
