The 4WE6W6X/EG24N9DK25L/62SO43A-1750 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It shifts hydraulic flow paths in NG6 circuits where compact size matters. A size 6 mounting face and the ISO 4401-03-02-0-05 porting pattern allow drop-in replacement on standard subplates, while the D03 NFPA interface supports North American manifolds. Positioning in the manifold is guided by an ISO 8752-3×8 pin locating hole to keep the lands aligned with the ports. The coil is energized from a 24 V DC supply; at this voltage the solenoid draws a rated current of 1.25 A and consumes 30 W, delivering consistent actuation force. Voltage may vary within ±10 % without loss of function, and the 100 % ED duty cycle permits continuous energization during long machine cycles. With both solenoids installed the unit weighs 1.95 kg, so tool-free handling is possible during service.
The hydraulic section is sized for a continuous flow of 80 l/min, so cylinder speeds remain stable on medium-capacity machines. Pressure limits are defined at 350 bar for the A, B, and P work ports and 210 bar for the T tank port, enabling safe operation in high-pressure systems while protecting the return line. An IP65 protection class seals the enclosure against dust and low-pressure water jets, making the valve suitable for exposed factory cells. Coil energy is released without damaging spikes because the circuit withstands switch-off overvoltages up to 500 V. These parameters enable reliable directional control in automated hydraulic stations where constant duty and electrical robustness are required.
