Pressure Compensation

The flow across any hole is determined by the pressure drop or differential pressure across the hole and the temperature of the fluid. Pressure compensation keeps the pressure drop across the hole relatively constant regardless of the inlet or outlet pressure at the hole.

True statement with one added emphasis.
If the Pressure drop across the Flow Control Orifice drops below the the Bias Spring Force the Pressure Compensator Spool opens fully and valve flow now acts like a non-compensated type.
