4WE6HA6X/EG24N9DK24L1/62SO407

The 4WE6HA6X/EG24N9DK24L1/62SO407 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is intended to shift hydraulic flow paths in automated machinery. It follows the ISO 4401-03-02-0-05 porting pattern, enabling direct mounting on size 03 subplates without adapter blocks. A 24 V DC solenoid energizes the spool, and the ±10 percent voltage tolerance keeps coil force consistent when the supply varies. Electrical power draw is limited to 8 W, which lowers control cabinet heat and wiring requirements. Connection is made through an M12 × 1 four-pole plug that provides quick-disconnect service loops. An integrated indicator light shows coil energization so maintenance staff can confirm command signals visually. The valve includes an interference protection circuit that suppresses voltage spikes and radio-frequency noise generated during switching. Compliance with protection class III under VDE 0580 gives reinforced insulation between the coil and housing, reducing shock risk in mobile or stationary installations.

The unit can run at a 100 percent duty cycle (S1), allowing continuous energization without thermal derating during extended machine cycles. Hydraulic limits reach 315 bar on pressure, A, and B ports, while the tank port withstands up to 210 bar, supporting high-pressure circuits found in presses and injection systems. A maximum flow of 60 liters per minute passes through the metering slots, maintaining response speed without excessive pressure drop. Switching is rated at two cycles per second, giving predictable dynamics for rapid but not high-frequency directional changes. The coil surface may reach 85 °C during service, and installation layouts must ensure ambient conditions do not exceed this temperature. Housing design meets IP65, blocking dust and low-pressure jets of water so the valve can be used near coolant spray or outdoors. A concealed manual override lets technicians shift the spool during commissioning or power loss while preventing accidental actuation in normal operation.
