The 4WE6D6X/OFEG24N9K4/B12 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth. It directs hydraulic flow to actuators in automated machinery where compact NG6 interfaces are required. The size 6 body matches subplates drilled to ISO 4401-03-02-0-05, so installation aligns with common manifold layouts. A maximum flow rate of 80 l/min allows the valve to handle medium-duty circuits without excessive pressure drop. Working ports P, A, and B tolerate pressures up to 350 bar, which supports high force cylinders. The tank port is limited to 210 bar to protect return-line components. A throttle insert of 1.2 mm is factory fitted in port P, providing initial metering and damping during spool shifts. The spool is held in either extreme position by a detent because no spring return is fitted. A concealed manual override lets technicians move the spool during setup while preventing accidental actuation in service.
The wet-armature solenoid operates from a nominal supply of 24 V DC and accepts a ±10 % voltage variation, enabling use on unregulated machine power. At that voltage it draws 1.25 A, corresponding to a nominal coil power of 30 W, which defines the electrical load on the control cabinet. The coil surface may reach 120 °C under continuous duty, so ambient layout must allow for heat dissipation. Electrical connection is through a DIN EN 175301-803 rectangular plug, simplifying wiring with standard cable glands. The same connector seals to an IP65 rating, giving dust-tight protection and guarding against low-pressure water jets. When mounted with proper gasket the enclosure seal maintains the stated ingress rating. These electrical features ensure reliable switching performance that complements the hydraulic ratings described above.
