The 4WE6G73-6X/EG96N9K4/62 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and directs hydraulic flow in automated machinery. It mounts on subplates that follow the ISO 4401-03-02-0-05 (D03) pattern, allowing straightforward interchange with other D03 components. The unit handles flow rates up to 60 l/min and tolerates 350 bar on pressure ports A, B, and P, while port T is limited to 160 bar for safe tank return. Continuous service is supported by a 100 % duty cycle, and the hydraulic medium must meet ISO 4406 class 20/18/15 cleanliness. Electrical excitation requires 100 V AC at 50 or 60 Hz with a ±10 % voltage window, drawing a rated current of 0.31 A under nominal conditions.
The solenoid assembly carries an IP65 enclosure rating with the K4 sealing configuration, resisting dust ingress and water jets. Coil surface temperature may reach 120 °C during sustained load, so neighboring components must tolerate that heat. Initial energization demands 220 VA, after which holding power falls to 50 VA for efficient continuous operation. A concealed N9 manual override lets technicians shift the spool mechanically when electrical power is unavailable. Built-in suppression withstands switch-off overvoltages up to 500 V, protecting control electronics from inductive spikes. These features combine hydraulic capability with robust electrical characteristics for dependable performance in automated press, molding, and machine-tool circuits.
