The Bosch Rexroth 4WRZ10EA85-7X/6EG24XEJET/D3V (R901041051) is a high-performance pilot-operated proportional directional valve designed for precise control over hydraulic flow direction and magnitude. This model, equipped with a type DREP pilot control valve, employs proportional solenoids that are controllable wet-pin DC solenoids, managed by external control electronics. The valve's structure includes a housing with a connection surface, a control spool with pressure measuring pins, and central thread solenoids. The functionality of the 4WRZ10EA85-7X/6EG24XEJET/D3V allows for pressure settings in ports A or B through the proportional solenoids, which vary according to the current supplied. In its default state with de-energized solenoids, the control spool remains in the central position due to compression springs, ensuring an unobstructed flow of hydraulic fluid back to the tank. When activated, one of the solenoids induces movement in the pressure measuring pin and consequently the control spool, creating an opening from P to A and B to T through orifice-type cross-sections featuring progressive flow characteristics. This model also features two spool positions (versions DREPA and DREPB), where only one solenoid is equipped alongside a plug screw in place of the second solenoid. For applications requiring precise manipulation of hydraulic systems within potentially explosive atmospheres, this subplate-mounted valve follows ISO porting patterns and offers spring-centered control spool functionality. The main valve includes a main control spool and centering spring that are proportionally controlled by the pilot valve. Designed for robustness and reliability in controlling flow direction and size, this Bosch Rexroth proportional directional valve is well-suited for sophisticated hydraulic applications demanding high levels of precision and responsiveness.
