The 4WE6D6X/OFEW110N9K4/V directional valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is applied to route pressure fluid in hydraulic automation systems. Its nominal size 6 establishes compact port geometry, while the ISO 4401-03-02-0-05 mounting pattern permits direct stacking on standard subplates. The valve sustains 350 bar on the pressure, A, and B ports and 160 bar on the tank port, allowing use in high-pressure circuits that still vent safely to the reservoir. A rated flow of 60 l/min fits medium-capacity actuators without excessive pressure loss. The solenoid is fed with 110 V AC at 50 or 60 Hz, and a ±10 % voltage tolerance keeps actuation reliable on fluctuating supplies. Connection is via a DIN EN 175301-803-A plug, and the enclosure meets IP65 to block dust and water jets. A concealed manual override marked N9 supports emergency shifting without accidental operation, and the assembled unit with two solenoids weighs 1.95 kg for straightforward installation.
At power-up the coil requires 220 VA switch-on power and then drops to 50 VA holding power to minimize continuous thermal load, and this transition also limits coil temperature rise over long duty periods. The design permits a switching frequency of two operations per second, supplying responsive control in repetitive machine cycles without overstressing the solenoid. FKM seals withstand common hydraulic oils and elevated temperatures, maintaining leak-tight performance. To protect the spool and bore from abrasion, the hydraulic fluid must satisfy ISO 4406 cleanliness class 20/18/15, so inline filtration is mandatory. These parameters enable the valve to perform consistent directional changes in automated manifolds while balancing energy consumption, durability, and contamination resistance.
