The 4WE6D6X/EW110DK25L valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow for automated actuators. The housing is designated size 6 and matches NFPA size D03 mounting blocks. A porting pattern of ISO 4401-03-02-0-05 aligns the pressure, tank, and actuator ports with standard subplate channels. Ports A, B, and P withstand operating pressures up to 350 bar, while port T is limited to 160 bar. The spool can pass up to 60 l/min without exceeding rated flow loss. Continuous service is supported by a 100 percent duty cycle, allowing uninterrupted shifting under load. With two solenoids installed, the assembly weighs 1.95 kg, which eases handling during manifold installation.
Electrical actuation is supplied at a nominal 110 V, 50 or 60 Hz, so the valve integrates with common control transformers. Each solenoid draws 220 VA during switch-on to generate the required magnetic force. Once the spool has shifted, power falls to 50 VA, reducing heat and energy demand. A DK25L five-pole Mini-Change connector provides a plug-in interface for the coil wiring. The coil surface may reach 120 °C under maximum loading, a factor to consider for adjacent components. An IP65 enclosure rating prevents dust ingress and protects against water jets when the gasketed connector is in place. The design supports up to two switching cycles per second, allowing 2 operations per second in high-frequency control loops.
