4WE6D6X/OFEW230N9K4/B10V

The 4WE6D6X/OFEW230N9K4/B10V directional spool valve is part of the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation systems that require compact flow control. The valve is built in size 6, so it fits installations that follow the ISO 4401-03-02-0-05 porting pattern. A D-type spool is fitted to establish the configured flow paths between pressure, tank, and work ports. Pressurized channels P, A, and B are rated for up to 350 bar, while the tank port t withstands 160 bar, enabling reliable operation in high-pressure circuits. The unit passes up to 60 l/min, supporting medium flow machinery without excessive pressure drop. A 1.0 mm throttle orifice is integrated in port P to limit inrush flow and dampen pressure surges. FKM seal material retains elasticity under elevated temperature and fluid exposure, maintaining leakage control over long service intervals.

Electrical actuation is supplied by a 230 V AC coil designed for 50/60 Hz networks, and the switch-on power requirement is 220 VA, so panel builders must provide an adequately rated supply. The coil is wired through a K4 connector that follows DIN EN 175301-803, facilitating quick replacement and standard cabling. Protection class IP65 safeguards the enclosure against dust and water jets when the connector is properly installed. A detent mechanism keeps the spool in its last energized position, and because of this feature no spring return is included. When manual intervention is required, a concealed N9 override permits local shifting without exposing the control to dirt or accidental contact. Together, these features combine electrical reliability with secure manual backup, ensuring the valve integrates cleanly into automated hydraulic manifolds.
