What’s this called?

What is the more accurate term? Are there any things to be careful about when using it? Thank you! ! !
Wow, this is the ball valve of Q341; it’s a two-piece design, and the device on top is the turbine switch! Why are points given even for wrong answers! This isn’t misleading people!
For butterfly valves, there is a gear connection in the radial direction on the face
It should be called a manual worm gear reducer; valve users also refer to it as a valve closing machine
For the turbine head, when turning the knob at the end, do not use excessive force – this can cause the internal positioning pins to bend and prevent accurate positioning
For the actuation device of valve switches, there are no specific requirements for manual valves; simply being able to switch them on and off is sufficient. Do not try to force them shut fully, as this can affect the sealing performance. For electric or pneumatic devices, it is necessary to pay attention to factors such as temperature and humidity in the operating environment!
It’s the turbine, which controls the degree of opening and closing; it can adjust the flow rate according to the operational requirements
