4WE6J6X/EG24NK4/V/62

The 4WE6J6X/EG24NK4/V/62 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and directs hydraulic flow in automation circuits where fast, repeatable positioning is required. The valve handles a maximum operating pressure of 350 bar on ports a, b, and p, allowing it to work in high-pressure supply manifolds. Its maximum flow of 80 l/min in direct-current operation defines the throughput the actuator group can receive without undue pressure loss. The ISO 4401-03-02-0-05 porting pattern standardizes manifold mounting and simplifies replacement. An FKM seal set resists mineral oils and elevated temperatures, maintaining leakage control during continuous duty. Protection class IP65 safeguards the coil and contacts against dust ingress and water jets, supporting installation in exposed machine areas. The DIN EN 175301-803 K4 connector aligns the valve with common wiring harnesses used on industrial machinery.

The solenoid is rated for a nominal voltage of 24 V DC with a permissible voltage deviation of ±10%, ensuring reliable pull-in when supply varies. During steady energization it draws 1.25 A, so panel designers can size power supplies and fusing accurately. Nominal power of 30 W quantifies the electrical load and the thermal output that must be dissipated through the housing. A duty cycle of 100% allows the coil to remain powered indefinitely without exceeding the 120 °C maximum coil surface temperature, which protects insulation life. The valve can endure a maximum switch-off overvoltage of 500 V generated by inductive collapse, so flyback suppression devices are optional rather than mandatory. Tank line t may be exposed to 210 bar in direct-current service, expanding mounting flexibility when back-pressure is unavoidable. Cleanliness class ISO 4406 20/18/15 defines the allowable particle count in the hydraulic medium, preventing spool sticking and premature wear.
