Bosch Rexroth Hydraulic Proportional Directional Control Valve R901004332. Pilot control valve type 4WRAP 6 W7.3X/G24. (1st stage) The pilot control valve is a direct operated proportional valve. The control edge geometry has been optimized for the use as pilot control valve for proportional directional valves type 4WRKE. The proportional solenoids are pressure-tight, wet-pin DC solenoids with detachable coils. They convert the electric current proportionally into mechanical force. An increase of the current results in a correspondingly higher solenoid force. The set solenoid force will remain constant over the entire control stroke. Any questions, please don’t hesitate contacting us.
