Which component can be pressure compensated on a non-pressure compensated system?

In a non-pressure compensated hydraulic system, a flow control valve is designed to regulate the flow of fluid while allowing for some flexibility regarding varying pressure conditions. Pressure compensation refers to the ability of certain valves or components to automatically adjust their operation in response to changes in system pressure. In a non-pressure compensated system, flow control valves can be adjusted independently of pressure influences, making them suitable to effectively manage flow rates while maintaining system performance.

Flow control valves often feature adjustable throttling capabilities, allowing them to modulate flow based on operational requirements without direct compensation for pressure changes. This allows for the management of hydraulic fluid flow in applications where maintaining a consistent flow rate is critical, and pressure may vary due to other factors in the system.

The other options present inherent characteristics that do not align with being pressure compensated in a non-pressure compensated system. For instance, pressure relief valves function to divert excess pressure, while check valves primarily allow flow in one direction without compensating for pressure variations. Displacement pumps are designed to move a specific volume of fluid per cycle and typically operate under pressure conditions, focusing mainly on fluid displacement rather than flow control in varying pressure scenarios.
