How do I choose between an expander and a pressure relief valve? Thank you

Hello everyone. My process involves reducing the pressure of gases, but I’m not sure whether to use an expander or a pressure regulator. How should I choose between the two? Are there any standard guidelines for this? hug:

It’s an obvious pressure relief valve… We specialize in its production; you can check my profile picture for more details·

Our company is designing a process, and the boss said an expander would work as well; I don’t even know what to use. Logically, either of the two will work

I would like to ask the original poster how an expansion joint can achieve pressure reduction

OMG, it’s not an expansion joint; it’s an expander. Either one will work, but the criteria or guidelines for choosing between an expander and a pressure relief valve aren’t very clear
