I have been asked to replace a small pressure relief valve with a seal/plug. The valve is composed of a brass case and some internal components, essentially a hollow cylinder with a spring loaded seal inside. The valve is press fit into a cast iron piece.
I have gone through the calculations and found dimensions for a plug that yield a similar assembly press force but I am wondering if this is best way to find a component with equivalent assembly properties. My concern is that the valve is hollow whereas the plug will be solid which changes internal stresses, among other things.
Would it be better to compare the ratio of assembly force to diameter, internal stresses, or something else?
Perhaps I'm overthinking this but, as I have limited experience with interference fits, I wanted to request input. I searched for similar situations on CR4 but didn't find anything.
