For rough adjustment of flow rate at an indefinite amount, which valve is the best choice?

For rough adjustment of flow rate without a precise value, which valve is the best choice? For example, when it comes to regulating the flow rate of cooling water, steam, heat transfer oil, etc., in the jacket of a reaction vessel, which valve is suitable – a globe valve, ball valve, butterfly valve, or gate valve? Why?
Apart from the steam stop valve being a bit better, all the other ball valves seem quite good.
Ball valves are mainly used for quick shutdown, not for regulating flow rate
The application scope is too broad; for ordinary use where cost is a concern and space is not an issue, choose a gate valve! Stop valves for steam regulation, cooling water, heat transfer oil; V-ball valves for regulation! It also depends on the medium’s corrosivity, viscosity, operating temperature, and the particle size of the medium! There are many comprehensive factors!
Butterfly valve, globe valve I guess. Forget about the ball valve
Considering overall operating conditions, valve characteristics, and economic factors: cooling water gate valves or butterfly valves, steam stop valves, heat transfer oil stop valves
