The 4WE6E73-6X/EG96N9K4/A12 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It routes hydraulic flow to actuators and returns fluid to tank in automated machinery. The coil is designed for a nominal voltage of 96 V DC so control cabinets with that supply can drive the valve directly. During energization it draws a rated current of 0.33 A, resulting in a nominal power consumption of 30 W that must be considered in power budgeting. A voltage tolerance of ±10 % allows stable performance when the supply varies slightly. Wiring is simplified by a DIN EN 175301-803 connector with three poles and protective earth, which accepts common molded plugs. The unit follows the ISO 4401-03-02-0-05 mounting pattern, enabling quick installation on NFPA D03 sub-plates. Continuous operation is possible because the solenoid is specified for a 100 % duty cycle.
For service and commissioning a concealed manual override labeled N9 permits shifting the spool without electrical power. An IP65 enclosure protects the internal parts against dust and low-pressure water jets, so the valve can be placed near fluid spray zones. The coil surface can reach up to 120 °C during extended energization, so adjacent components must tolerate that temperature. Hydraulic ratings include a maximum operating pressure of 350 bar on ports A, B, and P, a tank port limit of 210 bar on port T, and a continuous flow capacity of 80 l/min, which defines the size of the circuit it can control. The spool can change state up to 4.2 times per second, supporting moderate cycling applications. Overall mass is 1.95 kg, allowing mounting by a single technician without lifting equipment.
