Do manual ball valves come with a turbine drive?

Yes, it depends on your choice; generally it’s for DN200 and above
I’ve seen DN50 turbines of various sizes
Generally, turbines should be used for calibers of 150 and above; often, this is due to cost considerations. Using a turbine makes it easier and doesn’t cost much more
Yes, generally valves with a DN200 size come equipped with turbine drive
For ball valves, turbines are generally required when the pressure rating is 150~200 or higher.
For medium and low-pressure valves with floating ball design, turbines should be considered starting from DN150; for high-pressure ball valves or those with fixed ball design, it is recommended to use turbines starting from DN100.
