The 4WRTE32E600P-4X/6EG24K31/A1M is a proportional directional control valve produced by Bosch Rexroth for the 4WRTE Directional Control Valves series. It meters hydraulic flow for automation circuits that need precise cylinder or motor positioning. Valve size 32 provides large flow paths suited to high-capacity manifolds. A rated flow of 600 l/min at a 5 bar control-edge pressure drop allows stable motion control in medium pressure systems, while a linear characteristic with fine control (P) enables predictable spool response to small command changes. Ports P, A, and B withstand operating pressures up to 350 bar so the unit can handle heavy-duty actuator loads. The porting pattern follows ISO 4401-10-09-0-05, permitting direct mounting on standard subplates. Spool position is commanded by an analog ±10 V interface A1, and the solenoid coil is powered from a nominal 24 V DC supply through a DIN EN 175201-804 connector.
Environmental and electrical limits are defined for reliable service. An IP65 protection class shields internal parts against dust and water jets during machine operation. The coil can reach 150 °C without losing insulation strength, and maximum current draw is limited to 1.6 A to stay within typical power supply ratings. Pilot oil is taken internally, but return oil is routed externally through port Y, keeping pilot flow independent of tank pressure. The pilot stage accepts supply pressures up to 315 bar, and the external return line must not exceed 250 bar at port T. For installations needing higher displacement capability, the manufacturer recommends limiting total flow through the main stage to 1600 l/min so the valve remains within dynamic performance limits.
