​

• Specifiion

• Key functions 

1.Flow-Pressure Matching: Eliminates "energy waste" by adjusting pump flow to match the task’s pressure needs—no more excess flow (which wastes fuel) or insufficient flow (which slows operations).

2.Smooth Operation: Prevents sudden flow spikes or drops when the machine switches between light and heavy tasks (e.g., moving from idle to digging), ensuring smooth, jerk-free movement of the boom or bucket.

3.System Protection: Acts as a secondary safety mechanism to limit pressure—complementing the main relief valve by reducing flow before pressure reaches dangerous levels.

4.Fuel Efficiency: By optimizing pump displacement, it reduces the engine’s workload (the pump doesn’t have to push unused oil), lowering fuel consumption during long workdays.
