Properly sized relief valves … Tīmeklis2024. gada 4. nov. · The valve will close when the inlet flange pressure drops to 93-psig (100 – 7). Assuming inlet pressure losses of 3%, the system pressure at closing will be 96-psig (93 + 3). Now, assuming that inlet losses are 10-psig, the valve will close at 103-psig, which is 3-psig higher than the set pressure.
