Mechatronics Practice Test

To decrease actuator speed, you should turn the flow control valve clockwise.

Clockwise Counterclockwise Upwards Downwards

Correct Answer:

Clockwise

Explanation:

Controlling how fast an actuator moves hinges on adjusting the flow of fluid reaching it. A flow control valve acts as a throttle: when you tighten it by turning clockwise, the opening shrinks, reducing the flow rate and therefore slowing the actuator. Turning it counterclockwise widens the opening, increases flow, and speeds things up. Upward or downward movement isn’t how you adjust a flow-control valve, so those directions won’t change the speed. So, to decrease actuator speed, rotate clockwise.
