4WE6G11A6X/EG24N9K4

The 4WE6G11A6X/EG24N9K4 directional spool valve is part of the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation tasks that need precise on-off flow control. It uses a G-type spool with a center P to T flow path so that pump flow is unloaded to tank when the solenoid is de-energized. The body is drilled according to ISO 4401-03-02-0-05, allowing direct mounting on standard D03 subplates, while the corresponding NFPA T3.5.1 D03 pattern supports interchange with North American manifolds. The hydraulic ends tolerate up to 350 bar on ports A, B, and P, enabling use in high-pressure circuits, and the tank port withstands 210 bar to cover counterbalance or shock-reducing returns. A maximum flow capacity of 80 l/min in the DC configuration permits medium-size actuator speeds without excessive pressure drop. The N9 concealed manual override lets maintenance staff shift the spool without energizing the coil, which is useful during commissioning or power loss. A K4 electrical connector per DIN EN 175301-803 brings standardized wiring, and the same interface carries an IP65 rating to block dust and water spray in typical industrial environments.

The solenoid is designed for a nominal supply of 24 V DC, and a ±10 % voltage tolerance ensures reliable actuation under modest line variations. At this voltage it draws a rated current of 1.25 A, producing 30 W of magnetic power to shift the spool against spring forces and hydraulic pressure. Continuous service is possible because the coil is specified for a 100 % ED duty cycle, meaning it may remain energized indefinitely without thermal overload. Class F insulation resists winding temperatures associated with heavy use, and the external coil surface is limited to 120 °C to protect nearby hoses and wiring. These thermal limits are supported by the stated power level so that performance remains stable during long machine cycles. Together these electrical features complement the hydraulic ratings detailed earlier, creating a valve that maintains consistent switching behavior in automated presses, molding machines, and other motion sequences.
