Sure thing Mike - bursting disks (and possibly flow fuses) aren't common in the "generalist" building services sector - but in the sectors I tend to work in, it's never a bad thing to have a back up means of safety protection if things go horribly wrong - the big advantage of a bursting disk in conjunction with a spring seated PRV is they are incredibly unlikely to suffer a common mode failure. A bit like having 1250A HRC fuses up front in a switchboard equipped with ACB's - hopefully you never need them, but if you do, they will almost certainly work reliably even if they've been ignored for decades
