Which valve is used to maintain constant flow rate irrespective of load and is described as a two-way flow regulating valve?

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

Answer: (A)

To hold a constant flow rate in a hydraulic circuit regardless of load, you use a flow-regulating valve that automatically adjusts the opening to keep the set flow. The two-way flow regulating valve is designed for this purpose: it senses changes in downstream pressure and modulates the orifice so the fluid reaching the actuator stays at the preset rate, even as load pressure goes up or down. This compensation lets actuator speed stay essentially constant within the valve’s limits. A simple flow control valve by itself doesn’t compensate for downstream pressure changes, so the actual flow can vary with load. A restrictor is just a fixed orifice, giving flow that changes with pressure difference and isn’t capable of maintaining a constant rate. Meter-in describes how flow is directed into a component, not a device that enforces a constant flow across varying loads.
