Precise Proportional Control
These valves utilize proportional solenoid technology, which allows for stepless, infinite adjustment of hydraulic flow and pressure based on the input current signal. This provides smooth, accurate control over all machine functions – from fine grading to heavy digging – without the abruptness of on/off switching.
