Is there any difference between ball valve q341f and ball valve q41f in actual use? What is a turbine transmission?
Valve design standards have regulations on the amount of manual operating force. Valves with large torque require a reduction gearbox to reduce the manual operating force to within the regulations.
The driving methods are different. The q341f is a turbine drive, which is often used for high torque. The q41f is a handle drive. If you are not sure about the difference between the handle and the turbine, you can chat privately.

As far as I know, if the application handle is operated below DN80, a turbine drive is required for DN80 and above, otherwise it cannot be screwed :L
I think fixed ball valves with diameters above 50 are much more convenient to operate with turbines.； Floating ball valves with diameters above 100 are equipped with turbine heads.
The difference is the driving device, small-sized handle operation, large-sized worm gear, the specific dividing size is mainly related to the poundage class, and also related to the torque size of the specific manufacturer.
The first picture is Q41F, and the second picture is Q341F, which is the difference in transmission mode. Small-diameter valves can be opened and closed by driving with a hand lever. For large valves that cannot be operated by hand, a turbine must be added to open and close the valve. There are also pneumatic, electric, hydraulic, electro-hydraulic, gas-hydraulic drives, etc.
The largest handle ball valve I have ever seen is DN200, and the switch is very screwed! The most common specifications are 25/50/80
There is no difference in use, one is for the turbine and the other is for the handle.
