The 4WE6J73-6X/EG96N9K4/A12B08 directional spool valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation tasks that require reliable flow routing. With a nominal size of 6, it occupies minimal manifold space while still passing up to 80 l/min when the solenoid is energized. The porting pattern follows ISO 4401-03-02-0-05, allowing direct mounting on standardized subplates. A maximum operating pressure of 350 bar at ports p, a, and b permits use in high-pressure circuits, and continuous duty is supported by a 100 % duty cycle. Electrical supply is 96 V DC; at this voltage the coil draws 0.33 A so power consumption is held to 30 W. Environmental protection is rated at IP65, sealing the housing against dust ingress and water jets during routine wash-down or outdoor service.
A concealed manual override identified as N9 lets maintenance staff shift the spool mechanically without exposing the control surface. The valve connects through a K4 plug that complies with DIN EN 175301-803, simplifying field wiring with widely available cable sets. A 0.8 mm throttle orifice in the pressure port moderates inrush flow to limit shock loads on downstream components. Switching time is intentionally extended by the A12 feature, giving hydraulic cylinders a gentler start when precise motion is required. The tank port tolerates back-pressure up to 210 bar, so return lines can be routed through restrictive filters without risk of damage. One solenoid weighs 1.45 kg, data that assists in calculating manifold support structures for mobile or stationary installations.
