Which valve type does not depend on load to regulate flow?

• A. Flow regulating valves
• B. Meter-in
• C. One-way control valve
• D. Restrictor

Answer: (A)

The main idea is keeping the fluid flow constant regardless of changes in the load. A flow regulating valve is designed to do just that: it sets a preset flow rate and uses internal adjustment to hold that rate steady even when the pressure or load on the actuator varies. In other words, it decouples the actual load it faces from the amount of fluid that passes through, so the actuator speed stays predictable.

In contrast, a meter-in setup throttles flow into an actuator but the actual rate still tends to depend on the load because the required pressure to move the load changes the flow through the metering path. A one-way (check) valve only controls the direction of flow and doesn’t regulate the amount of flow at all. A restrictor creates a fixed resistance and its flow is directly tied to the pressure difference across it, so changes in load or inlet pressure will alter the flow.

So the valve type that does not depend on load to regulate flow is the flow regulating valve. It maintains a constant flow despite variations in the load.
