Last, set the pump pressure compensator setting to the actual system pressure that is required. Remember, the system pressure relief valve must be set about 200 PSI above the pump pressure compensator setting, or the two pressure settings will fight each other. This would result in the system acting as if it were a fixed displacement system.

Pressure Compensated Flow Control Valves | Parker NA
FR101 is an adjustable pressure compensated flow regulator which compensates for varying loads and pressures in one direction but in the other direction flow is metered across a fixed orifice but not compensated. In order to allow pressure compensated flow control in one direction and full free flow in the opposite direction, Parker offers an internal check valve in the adjustable FC101 cartridge.

What is Pressure Compensated Hydraulics? - Definition from
Pressure compensated hydraulics is a technology that automatically reduces flow based on system pressure. Unlike pumps with load sensing hydraulics, pressure compensated pumps only respond to system pressure. Pressure compensation is a key concept in hydraulic systems. Hydraulic equipment is commonly used in trenchless construction operations.
