The 4WE6W73-6X/EG24N9K4/A12/62 directional spool valve is supplied by Bosch Rexroth within the WE Directional Spool Valves series. The valve shifts hydraulic flow paths to start, stop, or change fluid direction in automated circuits. It is built in nominal size 6, so it fits manifolds designed for NG6 cavities. The mounting interface follows the ISO 4401-03-02-0-05 porting pattern, which simplifies interchange with other NG6 components. Working ports A, B, and P withstand pressures up to 350 bar, while port T is limited to 210 bar, allowing safe return-line service. The design carries a continuous flow capacity of 80 l/min to support medium-duty actuators without excessive pressure drop. A duty cycle of 100 % ED permits uninterrupted solenoid energization during long machine cycles. The enclosure rating of IP65 protects the coil and core tube from dust and low-pressure water jets in harsh plant environments. With two solenoids installed, the assembly weighs 1.95 kg, which enables easy handling during manifold installation.
The valve uses a cleanliness class of ISO 4406 20/18/15, so incoming oil must be filtered to that level to prevent spool sticking. Electrical power is supplied through a DIN EN 175301-803 K4 connector, providing standardized mating with factory wiring harnesses. Positioning on the manifold block is secured by a locating hole conforming to ISO 8752-3x8-St, ensuring repeatable alignment after service. The manual override accepts tank pressure up to 50 bar, letting maintenance staff shift the spool when power is absent. Each DC coil is rated for 30 W, operates at a nominal voltage of 24 V DC, and draws 1.25 A during steady state. The coil tolerates supply variations of ±10 %, maintaining reliable actuation despite minor voltage fluctuations. These electrical attributes support consistent switching in mobile and industrial hydraulic systems.
