The 4WE6U12-6X/EW110N9DAL directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth. It directs hydraulic flow to actuators in automation circuits where compact D03 valves are required. With a nominal size of 6, the valve suits manifolds for medium flow rates. A high-power wet pin solenoid shifts the spool; the coil is rated for 110 VAC so it can be driven from common control transformers. During energization the solenoid draws 220 VA switch-on power to overcome initial magnetic reluctance, then drops to 50 VA holding power to limit heat and energy consumption. Continuous service is supported by a 100 % duty cycle, and the winding can reach a surface temperature of 120 °C before thermal limits are met. The hydraulic body attaches through the NFPA T3.5.1 D03 interface, while the ISO 4401-03-02-0-05 porting pattern aligns internal passages. System pressure capability extends to 350 bar on ports P, A, and B for high-pressure circuits.
The valve handles flow rates up to 60 l/min to accommodate moderate actuator demands. Switching can occur at 2 cycles per second, allowing rapid yet controlled sequencing. The tank port tolerates 160 bar, so back-pressure does not compromise sealing. An IP65 enclosure guards against dust ingress and water jets when the connector is fitted. Electrical hookup is made through a 1/2-14 NPT conduit entry, simplifying installation with standard wiring. A concealed manual override lets technicians shift the spool during commissioning or power loss without exposing moving parts. These characteristics define the operating envelope and support dependable hydraulic direction control in industrial equipment.
