It’s feasible; the outlets of our fire pumps and circulation pumps are butterfly valves
Yes, many water valves are butterfly valves
Butterfly valves with turbines should be fine; those that are simple switches without turbines may experience changes in their position due to vibrations.

A pneumatic actuator or an electric actuator with proportional-integral control is used to adjust the opening degree of the butterfly valve in order to achieve the desired flow rate.
It depends on what system you are using. Butterfly valves have relatively weaker sealing performance. If handling materials, ball valves or globe valves are the best choice.
Using a butterfly valve is completely fine; it depends on the level of precision required. If high precision is needed, it is recommended to use a pneumatic butterfly valve; otherwise, a regular manual butterfly valve will suffice
