4WE6J73-6X/EG24N9K4/A12/62

The 4WE6J73-6X/EG24N9K4/A12/62 directional spool valve is manufactured by Bosch Rexroth as part of the WE Directional Spool Valves series. It diverts pressurized oil to selected work ports in hydraulic automation circuits and follows the ISO 4401-03-02-0-05 mounting pattern for compatibility with standard subplates. The electrically actuated spool is driven by a 24 VDC coil that draws 1.25 A and consumes 30 W, so a compact power supply can be used. Because the duty cycle is rated at 100 % ED, the valve may remain energized continuously, and the coil surface can reach 120 °C without degrading the insulation. The hydraulic section accommodates 350 bar on ports P, A, and B, while the tank port tolerates 210 bar during direct-current service. A maximum flow of 80 l/min supports medium-size actuators with minimal pressure loss. When local intervention is required, a concealed manual override allows momentary spool shifting without dismantling protective covers.

Assembly is aided by a locating hole specified as ISO 8752-3×8-St, which positions the housing accurately on the manifold and prevents rotation under vibration. The solenoid circuit accepts a ±10 % voltage variation, maintaining reliable pull-in even when supply lines experience drops or surges. At switch-off, the winding can endure overvoltages up to 500 V, protecting the insulation system from inductive spikes generated by rapid de-energization. The maximum switching frequency of 4.2 operations per second sets the response limit for applications that require repeated directional changes in rapid cycles. Total weight with two solenoids is 1.95 kg, so installation on light aluminum blocks is feasible without additional support. These electrical and mechanical characteristics complete the functional profile and help designers match the valve to power supplies, manifolds, and motion sequences within automated hydraulic equipment.
