Are the two safety valves on a 30-cubic-meter vertical liquid carbon dioxide storage tank used simultaneously, or one is in use while the other serves as a backup?

On a 30-cubic-meter vertical liquid carbon dioxide storage tank, there are two safety valves of the same size installed; the valve in the middle can also be used to shut off one of them. Are these two safety valves used simultaneously, or is one used while the other serves as a backup?
Two are activated simultaneously to ensure that if one fails, the other can still enable a safe takeoff
One is in use and one is as a backup; the one in the middle is a three-way switching valve. If one of them needs to be repaired or maintained, it can be switched to the other safety valve, thereby ensuring the normal operation of the storage tank.
They are like two safety valves, and they generally don’t open at the same time. Once valve A opens, valve B will only open when its pressure reaches 1.05 times that of valve A! Some safety valves may indeed be set such that their opening pressures are two, with both opening at the same time!

The two are used in conjunction with each other to prevent damage to the equipment due to one of them failing to activate; for safety reasons, dual safety valves are required, with the same setting pressure for both.
