The 4WE6J73-6X/EW110RN9DA/62 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow in automation circuits and fits manifolds built to the ISO 4401-03-02-0-05 pattern. The size 6 mounting face keeps the envelope small while still allowing a maximum flow of 60 l/min. System ports a, B, and P can be pressurized up to 350 bar, and the tank port t accepts 160 bar when AC actuation is used, so the valve handles typical industrial pressures. A concealed manual override designated N9 lets maintenance staff shift the spool without power, and the locating hole with an ISO 8752-3x8-St pin ensures repeatable positioning during installation. The housing carries an IP65 protection class, preventing dust ingress and water jets in indoor machinery environments.
Electrical actuation is supplied by a 110 V coil that operates on either 50 or 60 Hz mains, removing the need for an external rectifier. The switch-on power peaks at 220 VA to move the spool rapidly, after which the holding power drops to 50 VA to limit heat rise. Rated currents are 0.52 A at 50 Hz and 0.39 A at 60 Hz, values matched to common control transformers. Continuous duty at 100 % ED allows the solenoid to remain energized indefinitely without thermal cycling. Because the duty is continuous, the valve maintains position reliably during extended machine cycles. With these electrical parameters, the spool shifts quickly and holds firmly while coordinating hydraulic actuators in automated presses and material handling systems.
