Proportional hydraulic directional control valve GPV 130

spoollever-operated

Unlike traditional circuits, the pressure signal on the actuator in Load Sensing is constantly received and used as a pilot reference point for distributors and pump control. Thus the hydraulic system works efficiently and every work section consumes sufficient energy compared to traditional circuits. Load sensing proportional directional control valves are actuated with electronic motors which can drive spool super fine. GPV proportional directional control valves makes movements of the application is smoother and reliable.
