The 4WE6D6X/OFEW110N9DA valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series. It directs hydraulic flow to actuators in automated machinery and is driven by a solenoid designed for a 110 V AC supply at either 50 or 60 Hz. The inrush requirement is a switch-on power of 220 VA, after which the solenoid stabilizes at a holding power of 50 VA to reduce heat generation. Continuous service is possible because the coil is rated for a 100 % duty cycle, and its surface temperature may reach up to 120 °C without exceeding design limits. Current draw stays at 0.52 A on 50 Hz lines and 0.39 A on 60 Hz lines, matching standard industrial control transformers. When equipped with two solenoids the assembly weighs 1.95 kg, which supports easy manifold mounting in compact control blocks.
This model handles system flows up to 60 l/min while maintaining directional control, and the pressure at ports A, B, or P can be as high as 350 bar. Return flow sees a maximum tank port pressure of 160 bar, allowing installation in circuits with elevated back-pressure. The valve conforms to the ISO 4401-03-02-0-05 porting pattern and matches the NFPA D03 interface so it can be bolted directly to common sub-plates. A concealed manual override identified by code N9 is included for commissioning or emergency actuation, and the allowed installation position is unrestricted, enabling horizontal or vertical mounting. These features combine to simplify integration into hydraulic automation systems where reliable solenoid control and standardized interfaces are required.
