The 4WRPE10EA80SJ-2X/G24K0/A1M valve is part of the 4WRP Solenoid Valves series produced by Bosch Rexroth for closed-loop hydraulic automation. It meters oil flow in proportion to an electrical reference so that actuators follow position or speed commands. A nominal size of 10 sets the mounting interface, while a rated flow of 80 L/min at a 5 bar differential offers medium-capacity throughput. The progressive flow characteristic lets the controller achieve fine resolution at low spool strokes and higher capacity at full stroke. An overlap-jump spool geometry reduces deadband for quick response. Ports follow the ISO 4401-05-04-0-05 pattern to match standard subplates, and working ports p, a, and b can be pressurized to 350 bar; the tank port withstands 200 bar. A 24 VDC supply powers the on-board electronics, which accept a ±10 V command signal; an input impedance of 100 kΩ minimizes load on the motion controller.
A permitted residual ripple of 2.5 Vpp on the supply keeps coil force stable and prevents unintended spool motion. A 3.15 A time-lag external fuse safeguards the drive circuitry against short-term inrush or fault currents. NBR seals contain the hydraulic fluid and resist common mineral oils, and an IP65 housing rating blocks dust and water jets encountered on machinery. Fluid temperature may reach 70 °C without degrading performance, allowing use with warmed return lines. The 4/2 design weighs 6.0 kg, so the manifold or bracket must support that mass during service.
