The 4WE6D6X/OFEW110N9K4 UR valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth. It directs hydraulic flow to actuators in automated machinery. The spool is shifted by a wet-pin, detachable coil solenoid, allowing quick replacement during maintenance. The coil is rated for 110 V AC at 50/60 Hz so it can be powered from standard control transformers. When energized the solenoid draws 220 VA at switch-on and settles to 50 VA holding power, limiting heat rise during continuous duty. A duty cycle of 100 % ED (S1) means the valve may remain energized without interruption. The coil surface can reach 120 °C, a limit that defines enclosure spacing and insulation selection. The directional valve mounts on subplates with the ISO 4401-03-02-0-05 (D03) porting pattern for interchangeability across manifolds.
The assembly handles a maximum flow of 60 l/min, supporting medium-size actuator circuits. Ports A, B, and P tolerate operating pressures up to 350 bar, while the return port T is limited to 160 bar to safeguard the tank line. Fluid entering the valve must meet cleanliness class ISO 4406 (c) 20/18/15 to prevent spool sticking. A concealed manual override identified by code N9 permits local actuation during commissioning or power loss. Electrical connection is made through a DIN EN 175301-803 K4 plug, providing a sealed and orientable interface. The two-solenoid configuration weighs 1.95 kg, which simplifies installation on compact manifolds.
