4WE6D6X/EG24K72L/B10

The 4WE6D6X/EG24K72L/B10 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth. The unit shifts flow paths in hydraulic automation systems to start, stop, or redirect actuator motion. It operates on a nominal voltage of 24 V DC so it can be powered directly from low-voltage machine supply rails. A rated current of 1.25 A matches compact driver modules and keeps conductor sizes small. With a nominal power draw of 30 W, the wet-pin solenoid generates the required magnetic force while the surrounding fluid provides cooling. Maximum operating pressure of 350 bar on ports A, B, and P allows the valve to control high-pressure circuits found in presses and mobile equipment. A maximum flow rate of 80 l/min handles medium flow applications without inducing excessive pressure loss. The ISO 4401-03-02-0-05 porting pattern enables direct mounting on standardized subplates for quick replacement. A throttle insert with a 1.0 mm orifice in port P dampens pressure surges at valve energization.

Oil cleanliness must be maintained at class 20/18/15 according to ISO 4406 to prevent spool jamming and premature wear. The coil is rated for a 100% ED duty cycle, permitting uninterrupted energization during long holding periods. An M12x1 four-pole connector designated K72L provides a compact, keyed interface for power and control signals. The enclosure achieves an IP65 protection class under EN 60529, sealing against dust ingress and low-pressure water jets. Tank port T withstands return pressures up to 210 bar in DC operation, allowing remote reservoirs or back-pressure systems. The valve can switch up to 4.2 times per second, which supports moderate pulsation tasks in cyclic machinery. Coil insulation tolerates switch-off overvoltages up to 500 V, safeguarding driver transistors from inductive spikes. Because the installation position is unrestricted, the unit can be mounted horizontally or vertically without affecting performance.
