    2015-3-6 · the pressure relief valve, therefore, is the process fluid. Once a condition occurs that causes the pressure in a system or vessel to increase to a dangerous level, the pressure relief valve may be the only device remaining to prevent a catastrophic failure. Since reliability is directly related to the complexity of the device, it is important that

    Therefore, if the set point for a relief valve is say, 1 bar(g), and the pressure in the relief header is 0.2 bar(g), then the relief valve will open when the pressure in the vessel it is protecting is 60 psig. Such a scenario could occur if a plant-wide upset has caused multiple vessels to discharge into the relief header at the same time.
