I have a question about pressure in case of check valve failure scenario, if we want to size PSV based on this scenario, what are down stream and upstream pressure of check valve we should use in sizing. To clarify more,for example in sizing psv for control valve failure, to find required relief load we consider that the upstream pressure of control valve is maximum operationg pressure and the downstream pressure is pressure for PAHH alarm. What about upstream and downstream pressure check valve failure scenario?
If any one has a reference, that will be more beneficial
