4WE6JA6X/EG24DK25L/62

The 4WE6JA6X/EG24DK25L/62 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation circuits. It is actuated by a solenoid that is designed for a nominal voltage of 24 V DC, letting the control cabinet use standard low-voltage supplies. During activation the coil draws a rated current of 1.25 A, resulting in an electrical consumption of 30 W that must be included in power budgeting. A continuous duty rating of 100% S1 means the solenoid can remain energized without a cool-down period, supporting long holding cycles on machinery. The electronics accommodate a voltage tolerance of ±10%, so stable switching is maintained when the incoming supply fluctuates within typical industrial limits. Internal sealing and cable grommets give the assembly an IP65 protection class, allowing installation in areas exposed to splashed oil or dust. The armature and return spring are optimized for a maximum switching frequency of 4.2 actuations per second, providing responsive directional control. When de-energized the coil can endure a switch-off overvoltage of up to 500 V, safeguarding the winding insulation against inductive transients.

The hydraulic section supports a maximum operating pressure of 350 bar on ports P, A, and B, making it compatible with high-pressure pump lines. The tank port is rated at 210 bar in direct current service, preventing case drain overloading during continuous duty. Flow capacity reaches 80 l/min on direct current operation, so the valve can handle medium-size actuator circuits without excessive pressure drop. The spool channels follow the ISO 4401-03-02-0-05 porting pattern, simplifying manifold mounting with standard CETOP 03 interfaces. For North American layouts it matches the NFPA T3.5.1 R2-2002 D03 interface, allowing cross-standard interchangeability. Hydraulic cleanliness must not exceed ISO 4406 class 20/18/15, ensuring the spool moves freely and seal wear is minimized. Electrical hookup is completed through a DK25L five-pole connector, which offers secure locking and rapid coil replacement. A locating hole formed to ISO 8752-3x8-St aids precise positioning of the valve body on the manifold to prevent misalignment and internal leakage.
