The 4WE6D46-6X/OFEG24N9K73LSO407 valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation circuits that require reliable directional control. It is built in size 6 to fit compact manifolds, and the ISO 4401-03-02-0-05 porting pattern aligns the body with common sub-plates. An NFPA D03 mounting interface further standardizes installation across North American equipment. Four main ports allow connection to pressure, tank, and two actuator lines, letting the spool shift flow between work ports. The coil is energized with 24 V DC, and the solenoid draws a nominal 8 W so cabinet power supplies remain lightly loaded. Continuous operation is possible because the electromagnetic assembly is rated for a 100 % S1 duty cycle. A concealed manual override identified as N9 permits local actuation without exposing moving parts, keeping the envelope clear of accidental contact.
Spool return is provided by a detent mechanism with no spring, meaning the valve stays in its last position after power is removed until an opposing force is applied. An IP65 enclosure resists dust ingress and low-pressure wash-down, allowing the unit to be mounted on exposed machine frames. During steady energization the coil surface may reach 85 °C, which defines clearance and wiring insulation requirements near the valve. Hydraulic limits include a maximum pressure of 315 bar on the pressure and work ports and 210 bar on the tank port when the unit is driven by direct current. Flow capacity reaches 60 l/min, matching medium-size actuators in presses or tooling fixtures. Switching frequency is limited to 1 Hz to balance magnetic response with oil dynamics. NBR seals are used throughout the sub-assembly to hold mineral oil and prevent leakage across the rated temperature and pressure ranges.
