The Bosch Rexroth 4WRZ32E520-7X/6EG24XEJET/D3V (R901234241) is a sophisticated pilot-operated proportional directional control valve designed to manage flow direction and magnitude with precision. This model features a pilot control valve, type DREP, which utilizes proportional solenoids for actuation. The solenoids are wet-pin DC types that rely on external control electronics for operation. This valve is composed of a housing with a connection surface, a control spool with pressure measuring pins, and central thread solenoids. It functions by setting the pressure in ports A or B through the proportional solenoids based on the current supplied. When the solenoids are de-energized, the control spool is kept in a central position by compression springs, allowing hydraulic fluid to return to the tank unimpeded. Activation of a proportional solenoid shifts the control spool, altering connections between ports and enabling precise pressure adjustments proportional to the electrical input signal. Upon deactivation of the solenoid, springs return the spool to its neutral position. The valve is available in two-spool versions—DREPA and DREPB—each equipped with only one solenoid and featuring a plug screw in place of the second solenoid. It's crucial to note that for valves of version DREP C, only one solenoid should be activated at any time, and care must be taken not to allow the tank line to run dry. The 4WRZ32E520-7X/6EG24XEJET/D3V valve's main valve includes a main control spool and centering spring that are controlled by the pilot valve. The main spool moves proportionally to electric input signals via pilot oil from either an internal or external supply source. Designed for subplate mounting with porting patterns conforming to ISO standards, this model possesses a spring-centered control spool and can be used in potentially explosive atmospheres due to its specialized design. Additionally, it boasts rotatable solenoid coils for flexible installation orientations.
