The 4WE6J6X/EW110N9DA/B12V valve is supplied by Bosch Rexroth as part of the WE Directional Spool Valves series. It is intended for hydraulic automation tasks where electrical actuation shifts a spool to direct flow between ports. Continuous operation is supported by a 100% ED duty cycle, so the coil may remain energized without downtime. A nominal supply of 110 V at 50/60 Hz drives the high-power wet-pin solenoid, and the circuit can tolerate voltage variations of ±10% without performance loss. Holding power is 50 VA, and heat generated at this load is handled by an insulation class H winding that permits a maximum coil surface temperature of 120 °C. The coil is linked through a cable gland sized 1/2-14 NPT, easing connection in control boxes. A concealed N9 manual override allows local actuation when power is unavailable.
Hydraulic performance is defined by a maximum operating pressure of 350 bar at ports A, B, and P, while port T is limited to 160 bar to protect the tank circuit. The valve passes up to 60 l/min when fully shifted, and a porting pattern compliant with ISO 4401-03-02-0-05 matches common sub-plates. A throttle insert with a 1.2 mm orifice in port P (designation B12) moderates inlet flow when required. FKM seals resist high temperature and aggressive fluids, extending service life in industrial machines. An IP65 enclosure rating blocks dust and low-pressure water jets, enabling mounting in exposed plant areas once the conduit entry is sealed. Together these characteristics complement the electrical features described earlier and confirm suitability for precise, repeatedly cycled fluid power distribution in automated systems.
