Emergency shutoff devices for hydrogen and chlorine pipelines in hydrochloric acid synthesis furnaces

I would like to ask my friends: in the safety standardization inspection, there is a requirement to install emergency shut-off devices on the hydrogen and chlorine inlet pipelines of hydrochloric acid furnaces. What kind of devices are these? What is the purpose or function of installing them? I sincerely hope that knowledgeable friends can offer some guidance. # + + . hcbbs
On-off valves are installed on the hydrogen and chlorine gas pipelines at the entrance of the synthesis furnace to quickly cut off the hydrogen and chlorine when the synthesis furnace is interlocked. It is mainly designed for safety.
The main purpose of installing shut-off valves on the hydrogen and chlorine pipelines of the hydrogen chloride synthesis furnace is to promptly cut off these pipelines in the event of a fire or explosion at the furnace, thereby preventing such incidents from spreading to the chlor-alkali system.
It’s chlorine gas, as well as hydrogen gas in the pipelines, along with shut-off valves to prevent safety issues resulting from emergency shutdowns or other accidents

I’d like to ask the fellow maritime professionals upstairs again: for the shut-off valve, a interlock mechanism is required. Is it better to use a pneumatic valve or a solenoid valve? What are the cascade control parameters you’re using?
The pneumatic valves used in our company have a too long stroke time; solenoid valves are better
