The relationship between ball valves and water hammer

There are various opinions: some say that ball valves suffer from severe water hammer effects (I agree with this, as they are structured at the same level; is this reasonable?), while others claim the opposite, that ball valves prevent water hammer. What exactly is the relationship between the two? Can you give a reasonable explanation? Also, I noticed that in the drainage system proposed by Spaisak, ball valves are used for both the inlet and outlet valves. Is this appropriate? Why not use a stop valve?
The typical maximum temperature that ball valves can withstand is 150 degrees; they can be used at temperatures below this value. If the temperature is higher, it is better to use globe valves instead
It shouldn’t have anything to do with the type of valve; it’s probably related to the speed at which the switch is operated
I also think it has something to do with the driving speed. . . . . . . . . . . . . . . . . . . . . . .
It should be fine, right? Ball valves are now widely used; they are not only easy to operate, saving time and effort, but also possess the function of control flow similar to that of globe valves. It is also easy to use as a lining, with a wide range of applications
The decisive factor is definitely the switching speed! But does the structure of the valve have an impact on it?
It’s still very beneficial to come to this forum every day; one can learn a lot from it
Compared to globe valves and stop valves, where lies the convenience in operation? :) If it’s not started using a turbine (I’ve encountered DN150 models that use levers to start them, and it’s extremely labor-intensive to operate them), starting it might be even more strenuous, right?

The steam pipeline cannot be used, but since the temperature in the drain pipeline isn’t that high, it should still be usable! Personally, I think it’s better to switch to a globe valve.
