4WE6D6X/EG24N9DK25L/62 CSA

The 4WE6D6X/EG24N9DK25L/62 CSA directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic automation where electric actuation selects flow paths. It fits the ISO 4401-03-02-0-05 porting pattern, allowing direct mounting on NFPA D03 sub-plates. The valve sustains a maximum operating pressure of 350 bar at ports A, B, and P so it can manage high-pressure circuits in industrial machinery. A continuous flow rate up to 80 l/min keeps actuators supplied during rapid cycles. The solenoids are energized from a 24 VDC supply, and each coil draws a rated current of 1.25 A to generate the magnetic force needed for spool shifting. An IP65 protection class shields the enclosure from dust and low-pressure water jets in typical plant environments. Wiring is completed through a DK25L five-pole electrical connector, which provides power and grounding points in a compact form.

The coil surface is limited to 120 °C so insulation and adjacent components remain within thermal limits during extended duty. A concealed N9 manual override lets maintenance staff shift the spool without energizing the coil when testing or during power loss. The 42 mm clamping length defines the space required between mounting screws, ensuring consistent tie-bolt tension across different manifolds. A locking pin designated ISO 8752-3x8-St secures the spool position in the solenoid core and prevents axial drift under vibration. Tank return lines are protected by a 210 bar maximum pressure rating at port T, allowing installation in systems with elevated back-pressure. NBR seals are fitted to resist standard hydraulic oils while maintaining low leakage. With two solenoids installed the assembly weighs 1.95 kg, supporting easy manual handling during assembly and service.
