The 4WE6J6X/EW24N9DA/62 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow in automated circuits by shifting a size 6 spool between supply and actuator ports. The valve tolerates operating pressures up to 350 bar in the P, A, and B lines, allowing it to control high-pressure systems without external pressure reducers. It bolts to a sub-plate that follows the NFPA T3.5.1 D03 mounting interface so it can replace other D03 valves without altering the manifold. Port connections comply with the ISO 4401-03-02-0-05 pattern to keep flow paths aligned with standard cavities. Actuation is provided by a high-power wet-pin solenoid that can be detached for coil replacement or service. Electrical supply may vary within ±10 percent of rated voltage, ensuring stable shifting even when supply lines fluctuate.
Continuous operation is supported by a 100 percent duty cycle rating, so the coil may remain energized indefinitely during machine cycles. Hydraulic fluid must meet cleanliness level 20/18/15 per ISO 4406 to protect the spool from abrasive wear. The valve installs in any orientation, which simplifies layout in crowded manifolds. A concealed manual override identified by code N9 lets technicians shift the spool during commissioning, although its use is limited to tank pressures not exceeding 50 bar. The coil surface may reach 120 °C under prolonged energization, so adjacent components must be rated for that temperature. Positioning on the manifold is secured by a locating hole and ISO 8752-3x8-St pin labeled /62, preventing rotation under line shock.
