Pressure relief valve safety considerations during design

[elephunk]

What are the main safety considerations during design of a pressure relief valve? and how would you go about diagnosing if they are incorrect?

Is the following correct?

Orifice diameter for a fixed pressure - How to diagnose if it wasn't correct?

What effect would a incorrect system pressure at minimum setting have? Would the system just not function?

Thanks,

You should design the PRV to an industry standard. You can also verify the that the orifice is the correct size with the same standard.

My first question is why are you designing a relief valve as opposed to purchasing it off-the-shelf? Second, what is the application? Third, what is the circuit that the relief valve is to be used?
