A non-compensated flow control valve will cause actuator speed to change in response to load in what way?

A non-compensated flow control valve will cause actuator speed to change in response to load in what way?

• A. Increase
• B. Decrease
• C. Remain unchanged
• D. Fluctuate unpredictably

Answer: (B)

Non-compensated flow control valves do not adjust for changes in pressure or load, so the actuator’s speed tracks the actual flow available. When the load on the actuator increases, more pressure is required to move it, which reduces the flow through the valve since it isn’t compensating for that change. With less flow reaching the actuator, its speed decreases. If the load were lighter, more flow would pass and the actuator would move faster, but the key point is that increasing load causes a drop in speed.
