The 4WE6J6X/EW110ND/V directional spool valve is manufactured by Bosch Rexroth as part of the WE Directional Spool Valves series. It directs hydraulic flow in automation systems, shifting the spool to connect pressure, work, and tank ports as commanded. The valve installs on an ISO 4401-03-02-0-05 interface, while port layout follows the NFPA T3.5.1 D03 pattern, making it interchangeable with common sub-plates. A maximum operating pressure of 350 bar can be applied at the P, A, and B ports, and the T port withstands up to 160 bar, so the unit fits medium-pressure circuits. During operation it passes up to 60 l/min without exceeding rated drop, provided the fluid reaches cleanliness class ISO 4406 20/18/15. An IP65 enclosure protects the solenoids and connections from dust and low-pressure water jets. When both solenoids are fitted, the assembled valve weighs 1.95 kg, supporting compact manifold layouts.
The dual AC solenoids run on a coil voltage of 110 V and accept either 50 Hz or 60 Hz supplies. Switch-on power reaches 220 VA to create the initial magnetic force, then holding power stabilizes at 50 VA for continuous duty. Rated current is 0.52 A at 50 Hz and 0.39 A at 60 Hz, matching typical control transformers. The windings are built to insulation class H, and the design supports a 100 percent duty cycle S1, so the valve may remain energized without thermal shutdown. This electrical specification allows reliable shifting frequency in automated hydraulic machines that run around the clock.
