A hydraulic fluid flow control circuit, controlling linear actuator speed during extension, with the pump operating at system pressure, is known as a __________.
Official USCG Answer & Rule Citation
Correct Answer: Option B — metered-in circuit
A metered-in circuit controls the speed of a linear actuator by restricting the flow of hydraulic fluid entering the actuator. Because the flow control valve is placed on the supply side, the pump must operate at system pressure to overcome the resistance created by the metering valve.
