4WE6E73-6X/EW110N9DK25L/62

The 4WE6E73-6X/EW110N9DK25L/62 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs pressure and return flow in hydraulic automation circuits that use an ISO mounting interface. The valve is built to nominal size 6, matching compact power units where space is limited. A porting pattern of ISO 4401-03-02-0-05 aligns the subplate ports with the internal spool lands for consistent sealing. The assembly carries a maximum flow capacity of 60 l/min so actuators can cycle quickly without excessive pressure loss. Working ports A, B, and P withstand up to 350 bar, while the T tank port is limited to 160 bar to protect reservoir plumbing. Fluid entering the valve must meet cleanliness class ISO 4406 20/18/15 to prevent spool sticking. A concealed manual override permits service technicians to shift the spool during troubleshooting, and an IP65 enclosure rating shields the solenoid from dust and water spray. The unit weighs 1.95 kg, enabling single-handed installation.

Electrical actuation relies on a 110 V AC 50/60 Hz coil that drives the spool when commanded by the control system. The coil accepts a ±10 % voltage swing, allowing operation on industrial lines that experience modest fluctuations. During energization it draws 220 VA of switch-on power to overcome magnetic reluctance, then settles to 50 VA of holding power to limit heat rise in continuous use. A duty cycle of 100 % ED confirms the solenoid can remain powered indefinitely without surpassing temperature limits, supporting applications that require sustained flow direction. The 5-pole Mini-Change connector designated DK25L provides a quick-disconnect electrical interface and maintains sealing integrity against oil mist. These electrical features combine with the hydraulic limits noted earlier to create a valve suited for repeatable, high-cycle service in press automation, machine tools, and mobile equipment manifolds.
