Should the safety valves on the circulating water pipeline be operated one at a time with another as a backup?

Does the safety valve on this need to be inspected last year, just like the one on the equipment? Is one unit sufficient, or are both a primary and a backup unit required? O(∩_∩)O Thank you
I’ve never seen a circulating water pipe equipped with a safety valve; I have seen them on fire-fighting water systems
Since installation has been chosen for the design, the management requirements for safety valves must be followed during use. Inspect once a year ； The two valves can be one in use and one as a backup, or both can be used.
We have only one safety valve here, located on the highest branch pipe. There are also several plate heat exchangers that remain in operation at all times, and the safety valve has never triggered. . .
I’ve never seen a safety valve that needs to be opened and closed repeatedly. Safety valve testing is carried out during major overhauls. Send a picture to take a look
