The 4WRZE10E50-7X/6EG24N9EK31/A1V proportional directional valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and modulates hydraulic flow and direction in automated systems. It accepts a ±10 V command signal so the spool can be driven symmetrically around center, and a 15 % command overlap forms a defined neutral zone before flow begins. Continuous cycling is possible because the duty cycle is 100 %. Internal electronics draw up to 1.8 A during steady operation, while a 3 A power pulse is available for fast spool shifts. The solenoid winding measures 2 Ω at 20 °C, matching common drive amplifiers. A stabilized 24 V DC supply powers the on-board electronics, and wiring is completed through a DIN EN 175201-804 connector. The housing is sealed to IP65, protecting the components from dust and low-pressure water.
The valve tolerates a main line operating pressure of 315 bar, with port Y pilot drain pressure limited to 30 bar, and an external drain at port T that can also withstand 315 bar. At a 10 bar pressure drop it delivers a nominal flow of 50 l/min, giving predictable actuator speed profiles. Mounting follows the ISO 4401-05-05-0-94 porting pattern, allowing direct placement on standard subplates. Permissible fluid temperature reaches 80 °C, covering most industrial hydraulic oils. The assembly weighs 8.0 kg, so supporting hardware must account for that load.
