4WE6EB6X/EG24N9K4QM0G24

The 4WE6EB6X/EG24N9K4QM0G24 is a solenoid-actuated directional spool valve in Bosch Rexroth’s WE Directional Spool Valves series, intended to route pressurized fluid to cylinders or motors in automated hydraulic machinery. The coil is designed for a nominal supply of 24 V DC so standard control cabinets can drive it without step-down converters. At this voltage it draws a rated current of 1.25 A and consumes 30 W, providing consistent magnetic force to shift the spool. A voltage tolerance of ±10 % allows stable operation despite minor supply variation, while a duty cycle of 100 % ED permits the coil to remain energized continuously during long machine cycles. Thermal limits are defined by a maximum coil surface temperature of 120 °C, guiding enclosure ventilation and ambient temperature limits. The electrical housing meets an IP65 protection class that resists dust ingress and low-pressure water jets common on factory floors. For manifold mounting, the valve follows the ISO 4401-03-02-0-05 porting pattern, and the screws that secure it require 7 N·m of torque to maintain sealing without distorting the sub-plate.

The hydraulic section supports a maximum operating pressure of 350 bar at ports A, B, and P, enabling use with high-pressure pump circuits found in presses, molding machines, and general industrial handling equipment. Port T is limited to 210 bar so return-line plumbing and cooler selection must match this lower rating. When powered by direct current the spool can switch up to 4.2 times per second, allowing moderately fast reciprocating motion where position accuracy is governed by external sensors. The internal flow galleries accommodate up to 80 l/min, matching medium-size actuator requirements without excessive pressure loss or cavitation. A manual override is included and can be used while the tank line is below 50 bar to mechanically shift the spool during commissioning or emergency shut-down procedures. System cleanliness must reach ISO 4406 class 20/18/15 or better so that clearances remain free of abrasive particles over extended service life.
