4WE6D6X/EG125N9DK6L

The 4WE6D6X/EG125N9DK6L directional spool valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It controls start, stop, and directional change of hydraulic flow in automated machinery. Nominal size 6 limits the envelope so the valve fits compact manifolds while still handling substantial flow. The body bolts onto subplates drilled to the NFPA T3.5.1 D03 mounting pattern, and its ISO 4401-03-02-0-05 porting layout matches a wide range of interchangeable components. Actuation is provided by a wet-pin high-power solenoid that operates on 125 VDC; the coil draws a steady 0.17 A and consumes 30 W, permitting responsive shifting without excess heat. A ±10 percent voltage tolerance keeps performance stable when supply levels fluctuate. Hydraulic passages accept up to 80 liters per minute, and the housing is rated for 350 bar operating pressure, enabling the valve to serve medium-pressure circuits in presses, machine tools, and mobile equipment.

For continuous operation the solenoid is specified for a 100 percent ED duty cycle, so it may remain energized indefinitely during holding or cycling tasks. The enclosure carries an IP65 rating, which blocks dust ingress and withstands water jets encountered in industrial wash-down areas. Electrical hookup is achieved through a DK6L seven-pole connector that follows DIN EN 175201-804, providing secure, keyed engagement for control cables. An N9 concealed manual override sits beneath the end cap, allowing technicians to shift the spool by hand during setup or power loss without removing wiring. Dynamic sealing is handled by NBR elastomers that tolerate common mineral oils and standard fluid temperatures. When the coil is de-energized the winding can absorb switch-off transients up to 500 V, protecting insulation from inductive spikes generated by fast electronic drivers. Together these attributes let the valve deliver reliable, leak-tight service in automated hydraulic systems that demand precise, long-term flow control.
