The 4WE6D6X/EG24N6K4QMBG24 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation tasks that require precise on-off flow control. The electromagnetic actuation relies on a 24 V DC solenoid that accepts a ±10 % voltage window, and the coil draws 30 W during operation. Continuous service is supported by a 100 % duty cycle (S1), allowing the valve to remain energized without thermal pauses. Electrical connection is made through a K4 plug conforming to DIN EN 175301-803, while an IP65 enclosure rating protects internal components from dust and water jets. The housing mounts to sub-plates with the ISO 4401-03-02-0-05 porting pattern, and the flow passages accommodate up to 80 l/min, making the unit suitable for medium-capacity circuits.
A large, non-lockable mushroom-style manual override identified as N6 lets maintenance personnel shift the spool locally even when electrical power is absent; this override can be used against tank pressures reaching 50 bar. When controlled electrically, service ports p, a, and b withstand working pressures up to 350 bar, while the return port t is limited to 210 bar. The magnetic system changes state at rates up to 4.2 operations per second, supporting rapid cycling requirements. Spool position feedback is provided by a QMBG24 switch that senses the “b” position and issues a 24 V DC signal to external controllers. During sustained energization the coil surface may reach 120 °C, a temperature the insulation system is designed to tolerate without degradation.
