The 4WE6D6X/OFEG24N9K4/B06 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and shifts hydraulic flow paths in automated machinery. It bolts to subplates with the ISO 4401-03-02-0-05 interface so replacement parts remain interchangeable across manifolds. A 24 V DC solenoid drives the spool; the ±10 % voltage tolerance keeps actuation reliable when supply levels vary. The coil draws 1.25 A and consumes 30 W, providing the magnetic force required while staying within standard power budgets. Continuous energization is supported by a 100 % duty cycle, and insulation class F together with a maximum coil surface temperature of 120 °C prevents thermal damage during long operating periods.
A K4 connector conforming to DIN 175301-803 simplifies field wiring, while an IP65 enclosure rating blocks dust and low-pressure water for dependable outdoor or wash-down service. The OF detent holds the spool in its last switched position after power is removed, useful for circuits that must maintain flow direction during outages. High-pressure capacity is defined by a 350 bar limit on ports p, a, and b; the tank line may return at up to 210 bar. Flow can reach 80 l/min, and a 0.6 mm throttle insert in the pressure port moderates inlet surges. With two solenoids installed the valve weighs 1.95 kg, enabling manual handling during assembly or service.
