Normally, hydraulic system uses proportional pressure and speed valve controlling system, which the machine pressure and speed is controlled by the computer setting and does not have circuit feedback correction function.

The closed-loop machine uses "BOSCH" brand high speed PQ valve to control each pressure and speed action at closed-loop condition.
The PQ proportional valve follows the pressure and speed feedback to automatically correct the pressure and speed respectively all the time to ensure a strong stability pressure and speed output.
The flow control uses balance pressure circuit valve to minimize the pressure drop that caused by the difference of oil temperature.
The hysteresis decreases to 0.3% while non-high-speed valve is 3%, therefore, the PQ proportional valve has good linearization, good responsiveness, high reproductivity, and well maintained stability.
