The 4WE6G73-6X/EW110RN9DAL/A12/62 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation tasks that require reliable on-off control of actuator flow. It is designed for a 110 V AC supply, and its coil accepts either 50 or 60 Hz line frequency so that the same model can be used in different regions. The switch-on power draw of 220 VA produces the magnetic force needed to shift the spool, after which the holding requirement falls to 50 VA to reduce heat and energy use. A 100 % duty cycle permits the valve to remain energized continuously without exceeding thermal limits. Electrical leads are brought in through a 1/2-14 NPT cable gland that keeps the enclosure sealed, and the housing is rated IP65 to block dust ingress and water jets in typical industrial environments.
The hydraulic section passes up to 60 l/min when the spool is actuated, and the pressure limit on ports P, A, and B is 350 bar to suit high-pressure circuits, while the tank port may be exposed to 160 bar in AC service. Installation matches NFPA D03 subplates, and the port face follows the ISO 4401-03-02-0-05 pattern for interchangeability across different manifolds. A locating hole prepared to ISO 8752-3x8-St ensures precise centering during mounting, and a concealed manual override lets technicians shift the spool for testing without disturbing external piping. With two solenoids installed the assembly weighs 1.95 kg, allowing single-person handling during maintenance.
