    The process itself determines the requirements.
    Generally a process line needs a relief valve to maintain sufficient pressure for the process to function (backpressure) and/or to protect the process from overpressure of the weakest component exposed to the process including the safety factor(s). The relief system should be sized for the process; such as pressure, temperature, volume, construction material for corrosion, characteristics of "load/unload", etc.. .
