The 4WRPE10W50SJ-2X/G24K0/F1M valve belongs to the 4WRP Solenoid Valves series and is produced by Bosch Rexroth. It is a proportional directional control valve for hydraulic automation, adjusting flow based on an electrical command. The unit is built in nominal size 10 so it fits manifolds designed for that passage dimension. Its mounting pattern follows ISO 4401-05-04-0-94, allowing direct installation on standardized subplates. A 24 V DC supply powers the integrated electronics while a 4-12-20 mA current command signal sets the spool position, enabling closed-loop control from common PLC analog outputs. The input shunt resistance is 200 Ω, defining the electrical load seen by the controller. A step change of 100 % is answered in 40 ms, giving adequate dynamic response for motion sequences. The spool uses a progressive flow characteristic, providing fine resolution at small displacements. Under a 5 bar differential the valve passes a nominal flow of 50 l/min, supporting medium-capacity actuator circuits.
The overlap compensating signal coded J minimizes flow deviation around the neutral point, aiding steady actuator positioning. Environmental sealing reaches IP65, so water jets and dust do not enter the housing during field service. Electrical power and feedback are routed through a 6P+PE connector conforming to DIN 43563-AM6, giving a keyed interface for quick replacement. Ports p, a, and b are rated for a working pressure of 315 bar, while the tank port endures up to 200 bar, allowing the valve to operate in high-pressure circuits without structural reinforcement. Internal leakage is limited to 80 cm³ per edge each minute at a 100 bar drop, preserving pump efficiency when spools are centered. The hydraulic fluid must meet cleanliness class ISO 4406 18/16/13 to prevent wear of the metering lands. With a mass of 8.3 kg the assembly can be handled by one technician yet remains rigid under vibration once bolted to the manifold.
