The 4WRP10E63S-1X/G24Z4/M solenoid valve belongs to the 4WRP Solenoid Valves series and is produced by Bosch Rexroth for closed-loop hydraulic automation. It meters flow to servo cylinders through a sliding spool controlled by an integrated proportional solenoid. The unit installs on an ISO 4401-05-06-0-94 (NG10) interface, so it matches common NG10 subplates. With a nominal flow of 63 l/min at a 5 bar drop per notch, it maintains consistent actuator speed. Ports P, A, and B withstand working pressures up to 315 bar, while the tank port rating is 250 bar, ensuring correct line sizing. The separate drain port tolerates only 2 bar, which limits backpressure on the pilot stage. Command accuracy is helped by a maximum hysteresis of 0.75%, and a 50 ms response for a 100% step supports fast positioning loops. Internal leakage is limited to 80 cm³/min at a 100 bar differential. An IP65 enclosure protects the coil and spool assembly from dust and water.
The solenoid is powered by a 24 V DC amplifier and can draw as much as 60 VA, with current peaking at 3.7 A to produce full spool force. The moderate electrical demand allows the valve to run from standard machine power supplies, yet the available amperage secures rapid actuation. Electrical hookup uses a DIN 43650/ISO 4400 connector with an M16×1.5 thread, providing quick service access and clear polarity coding. NBR sealing elements contain hydraulic oil and resist most standard fluids used in industrial power units, limiting maintenance intervals. The construction withstands vibration levels up to 25 g, preventing inadvertent spool movement when installed on presses or mobile frames. Overall mass is 8.0 kg, so a single technician can remove or install the unit without lifting aids while still ensuring mechanical rigidity once bolted in place.
