handwheels
Rotating control discs
Handwheels is the plural of handwheel, a wheel turned by hand to operate machinery or adjust a mechanism.
Valves, lathes, and industrial equipment often use handwheels for manual control: She gripped the handwheel and slowly opened the valve.
The design allows for precise adjustment with moderate force.
