A meter-out flow control circuit controls the speed of an actuator by _____________.

In a meter-out flow control circuit, the speed of an actuator is controlled primarily by restricting the exhaust flow of air from the actuator. This setup allows the actuator to extend or retract at a controlled rate, preventing it from moving too quickly. When the exhaust path is restricted, the air that needs to leave the actuator does so at a controlled rate, which effectively creates back pressure in the actuator.

By controlling how quickly the air can leave the system, the actuator's movement speed can be moderated. This is especially useful in applications where precise movement is required, as it allows for smoother operation and avoids sudden jerks that could damage the system or its components.

Restricting the air flow to the actuator (the other choice) generally refers to controlling the input supply, which is not how meter-out circuits function. Instead, they focus on the exit of air to control speed.
