In this design, the pump control signal acquisition in the second pilot pressure, life and and it's back to the oil pressure is just back pressure, so this control system for excavators operating sensitivity, and more fuel-efficient.

In this design, pump control signal acquisition from the second pilot pressure, oil pressure and it is just back pressure, so the control system of excavator operation sensitivity not only good, and fuel economy.

In this design, pump control signal gathering in two forerunner pressures, moreover its oil discharge pressure is merely a back pressure, not only therefore has this control system excavator the operation sensitivity to be good, moreover comparison province oil.

In this design, the pump control signal acquisition in 2 pilot pressure, and it has a back pressure is just back-pressure, so we have this control of the system's excavator operating sensitivity not only good, but also more fuel-efficient.

In this design, pump control signal acquisition from the second pilot pressure, oil pressure and it is just back pressure, so the control system of excavator operation sensitivity not only good, and fuel economy.
