4WE6J6X/EG24N9K73L/62

The 4WE6J6X/EG24N9K73L/62 is produced by Bosch Rexroth within the WE Directional Spool Valves series to shift hydraulic flow between actuator paths in automated machinery. It follows the porting pattern ISO 4401-03-02-0-05, allowing direct mounting on standard subplates without extra adapters. The internal passages require oil cleanliness at ISO 4406 20/18/15 so that spool wear remains low during continuous service. A nominal voltage of 24 V DC aligns the solenoid with common control power supplies. The voltage tolerance of ±10% provides stable function despite minor fluctuations on the machine bus. During actuation the coil draws a rated current of 1.25 A to achieve consistent magnetic force. Nominal power consumption is 30 W, limiting heat generation inside compact manifolds. Electrical hookup is through an M12x1 4-pole connector with a suppressor diode, which simplifies wiring and protects electronics from inductive spikes. The enclosure meets IP65 so splash water and dust cannot enter the energized components. A locating hole sized for an ISO 8752-3x8-St pin ensures repeatable positioning on the manifold block.

The design supports a 100% ED duty cycle, enabling continuous energization without thermal derating. A maximum switching frequency of 1 Hz in the K73L version keeps response reliable in cyclic positioning tasks. This switching limit also prevents excessive armature wear during repetitive strokes. Pressure ratings reach 350 bar at ports a, b, and p, allowing use in high-pressure circuits. The tank port withstands 210 bar in DC operation, which permits back-pressure without risking seal failure. Flow capacity up to 80 l/min lets the valve handle medium-size actuator demands with minimal pressure loss. That flow capability supports smooth motion of cylinders where moderate speeds are required. An MTTFd of 300 years provides a high reliability index for safety assessments in performance level calculations. A concealed manual override permits local shifting during setup while preventing accidental use in service.
