Which valve is described as regulating flow without regard to hydraulic load?

• A. Flow regulating valves
• B. Meter-out
• C. Counterbalance valve
• D. One-way control valve

Answer: (A)

If you need to set a specific rate of fluid flow that stays essentially the same even as the load on the hydraulic system changes, you use a flow regulating valve. Its job is to control how much fluid passes through a circuit, so actuator speed remains predictable regardless of the pressure created by different loads. That makes it the best fit for “regulating flow without regard to hydraulic load.” Meter-out valves also regulate flow, but the actual flow to the actuator tends to vary with the load because the pressure on the actuator side affects how much fluid can pass through the throttling path. A counterbalance valve is used to hold or control load position against gravity or other forces, not to regulate flow. A one-way control valve (check valve) only permits flow in one direction and doesn’t set a controlled flow rate independent of load.
