Dear masters, what are the set pressure values for the safety valves on the liquid oxygen storage tank drainage pipelines at atmospheric pressure, as well as on the inlet and outlet pipelines of the booster?

Dear experts, what are the set pressures for the safety valves on the liquid oxygen storage tank’s discharge lines, as well as on the inlet and outlet lines of the booster? The setting pressure for our safety valves is all 0.8 MP – is that okay? Does this have a standard code?
For the drain piping of the liquid oxygen storage tank at atmospheric pressure, a safety valve with a setting pressure of 0.8 MPa is sufficient, as this is similar to the setting pressure of the safety valves on the inlet and outlet pipelines of the booster; the specific value can be determined based on the design of the storage tank. If it is a safety valve located at the outlet of the liquid filling pump, it’s better to use one with a higher setting pressure.
0.8 is good enough! I think 0.6 is fine too! A residual pressure of 0.05 is sufficient
Generally, values below 1.0 Mpa (G) are acceptable; it mainly depends on whether the safety valve is installed at a high or low position, as well as the pressure to which it is exposed during use
