SIS valves are installed for material inflow and outflow at the storage tanks in the tank farm. Is it possible to install such valves on the main pipeline when there are multiple storage tanks holding the same material? Are there any regulatory guidelines regarding this?

I need help from experts. For the inlet and outlet valves of storage tanks in a tank farm, regulated by SIS systems, if there are multiple tanks storing the same material, can these valves be installed on a main pipeline, or must separate valves be installed at the inlet and outlet of each tank? Is there any relevant standard or guideline for this? Thank you
https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=3195738 An emergency shut-off valve, as the name implies, is used to achieve an emergency shutdown of storage tanks. Its main functions are: 1. Automatically closing the feed valve when the liquid level in the tank reaches a high level； 2. Automatically close the discharge valve when the liquid level in the storage tank is low ； 3. The accident condition allows for rapid remote disconnection from other equipment and devices, without the need for manual intervention by operators on-site (as it is often impossible for operators to access the site during an accident). Installing a shut-off valve for multiple storage tanks does not serve the above 3 purposes.
In my understanding, it’s possible when there are multiple storage tanks but only one is in use
