Why are valves installed at the gas inlet of the high-pressure reactor and at the reactor mouth, and what is the basis for this?

Dear friends from Haichuan: Why are valves required at the gas-phase inlet and the reactor outlet of high-pressure reactors? What is the basis for this? Which standard does it come from? Thank you all for your answers!
The addition of valves to the gas inlet and the reactor mouth of high-pressure reactors is mainly for the following reasons: controlling the amount of gas introduced, ensuring reaction safety, facilitating feeding and sampling, and preventing leaks during the reaction process. This approach is based on the general guidelines for the design of chemical processing equipment and safe operation, but it does not derive from any specific standard; rather, it is determined more by process requirements and safety considerations. Common relevant standards may include **or regional chemical engineering design standards, pressure vessel standards, and safety, health, and environmental standards, etc. .
