The 4WE6J6X/EG24N9K40SO43A-1799 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow in automated machinery. The NFPA T3.5.1 D03 mounting pattern lets the body bolt onto standard sub-plates, and the ISO 4401-03-02-0-05 porting pattern aligns the pressure and work ports with common manifold cavities. A 24 V DC coil draws 1.25 A, while a ±10 % voltage tolerance keeps actuation reliable on systems with fluctuating supplies. Nominal power is 30 W, limiting heat production, and a 100 % ED duty cycle permits continuous energization without forced cooling. Ingress protection is rated IP69K, so the housing resists high-pressure wash-downs, and a DT04-2PA Deutsch connector provides sealed, vibration-proof wiring. Insulation class F supports winding temperatures up to 155 °C, yet the external surface is restricted to 120 °C to safeguard surrounding hoses and wiring.
The valve operates at pressures up to 350 bar on ports A, B, and P, letting it manage high-pressure cylinders, while the tank port tolerates 210 bar to prevent damage when back-pressure rises. A maximum flow of 80 l/min allows medium-size actuators to move without undue restriction. A concealed manual override enables service personnel to shift the spool during testing or power loss, while remaining protected from accidental bumps in the field. The coil endures switch-off overvoltages to 500 V, shielding it from inductive spikes generated by drive electronics. These electrical limits, combined with the thermal design referenced earlier, secure long service life under repeated cycling. Together, these characteristics match the needs of hydraulic circuits that require reliable, wash-down-resistant actuation and straightforward integration into standardized manifolds.
