The 4WE6J6X/EG96N9K4/B10V directional spool valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It shifts flow paths in hydraulic automation by energizing a high-power wet-pin solenoid, which supplies reliable actuation force while staying immersed in system fluid for cooling. The coil is designed for a rated voltage of 96 V DC and draws a steady 0.33 A, allowing direct connection to medium-voltage vehicle or plant supplies. Electrical wiring is achieved through a DIN EN 175301-803 K4 connector, giving a standardized plug interface for rapid service replacement. An IP65 housing prevents dust ingress and low-pressure water spray from reaching internal parts, and FKM seals provide resistance to common hydraulic oils and elevated temperatures. System fluid must conform to cleanliness class 20/18/15 according to ISO 4406 to protect the precision spool. A 1.0 mm throttle orifice located in the P gallery limits inrush flow and smooths pressure rise when the valve shifts.
The unit follows nominal size 6 geometry and uses the ISO 4401-03-02-0-05 porting pattern so it can be mounted on standard sub-plates without re-machining. Four main ports allow connection of pressure, tank, and two actuator lines, giving the basic four-way control required for bidirectional cylinders or motors. Flow up to 80 l/min can be handled in the direct-current version, while the A, B, and P passages tolerate operating pressures as high as 350 bar. The tank port in DC service is limited to 210 bar, and an internal design cap keeps manual override use to applications where return pressure does not exceed 50 bar. The concealed manual override lets maintenance staff shift the spool mechanically during commissioning or power loss without exposing moving parts to contamination. These features combine to offer a compact valve that meets the pressure, flow, and mounting needs of modern hydraulic control manifolds.
