The 4WE6D6X/OFEW110N9K4/B25/62 valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth. It directs hydraulic flow between pressure, tank, and work ports to automate cylinder or motor movement in industrial machinery. A porting pattern compliant with ISO 4401-03-02-0-05 lets the valve mount on widely used NG6 subplates, simplifying manifold integration. The coil is designed for 110 V AC at 50 or 60 Hz, so it connects directly to standard plant power without a transformer. At 50 Hz the coil draws 0.52 A, while at 60 Hz the current drops to 0.39 A, information necessary for sizing control relays and circuit protection. An inrush demand of 220 VA ensures fast spool shift, and once energized the holding requirement falls to 50 VA to limit heat build-up. The electrical interface uses a DIN EN 175301-803 type K4 connector, providing a sealed plug connection that speeds service replacement. Continuous energization is possible because the solenoid is rated for a 100 % duty cycle, preventing thermal shutdown during long machine cycles.
The valve handles system pressures up to 350 bar at ports P, A, and B, which allows it to control high-force actuators. Flow capacity reaches 60 l/min, so it supports medium-sized circuits without excessive pressure loss. Tank port pressure is permitted up to 160 bar, enabling safe return flow in counterbalance or regenerative circuits. A concealed manual override identified by code N9 lets maintenance staff shift the spool when power is absent, and it may be used as long as tank pressure does not exceed 50 bar. The design switches up to two cycles per second, allowing rapid directional changes in automated sequences. A locking pin in the locating hole, designated /62, aligns the body on the subplate to prevent rotational movement during service. The B25 throttle insert with a 2.5 mm orifice is fitted in port P to restrict flow and smooth actuator acceleration.
