4WE6D6X/EG24N9K72LSO407

The 4WE6D6X/EG24N9K72LSO407 directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth. It shifts hydraulic flow paths in automation assemblies where compact solenoid actuation is required. A nominal voltage of 24 V DC lets the solenoid coil connect directly to common control supplies. The allowable voltage tolerance of ±10 % keeps switching behavior stable when the supply varies. With a nominal power draw of 8 W, the unit imposes minimal electrical load on the control system. Continuous energization is possible because the duty cycle is rated at 100 % ED. The coil surface may reach 85 °C, which defines enclosure design and thermal guarding needs. Environmental sealing up to IP65 prevents dust ingress and low-pressure water spray from affecting the coil and terminals. Standardization is supported through an NFPA T3.5.1 D03 mounting pattern and an ISO 4401-03-02-0-05 porting pattern, allowing the valve to fit common subplates.

Electrical wiring is simplified by a 4-pole M12 × 1 connector, which provides quick-disconnect capability during service. A switch-off overvoltage limit of 500 V safeguards the coil insulation and upstream driver electronics when the field collapses. The valve can cycle once per second at most, as indicated by a maximum switching frequency of 1 1/s, ensuring controlled actuation in sequential logic. Hydraulic channels p, a, and b withstand operating pressures up to 315 bar, enabling use in high-pressure circuits. Port T can accept 210 bar, so back-pressure in the return line does not impair spool movement within that limit. When energized with direct current, the assembly passes up to 60 l/min, matching medium-flow actuator demands. Manual override operations must keep tank pressure below 50 bar to avoid damaging the override mechanism. These hydraulic and electrical parameters combine to deliver predictable response for machine tools, presses, and other automated stations that rely on precise directional control.
