The Bosch Rexroth 4WRZ10W6-50-7X/6EG24N9EK4/D3WG152V-68 (R901193735) is a pilot-operated proportional directional valve designed to control the flow direction and size in hydraulic systems. This valve is characterized by its high responsiveness and precision in controlling flow, making it suitable for applications that require fine-tuned adjustments. It features proportional solenoids for actuation, which allow for smooth and proportional movement of the main control spool in response to electric input signals. The main control spool is spring-centered, ensuring that it returns to the central position when solenoids are de-energized. The valve includes an additional port R only for NG, which provides flexibility for various hydraulic circuit designs. It also offers an optional manual override function, which can be utilized to manually adjust the control spool without solenoid energization—though users must exercise caution due to potential uncontrolled machine movements. Designed with orifice-type cross-sections, this model ensures progressive flow characteristics, allowing for precise modulation of flow from P to A and B to T or vice versa depending on the spool position. The pilot oil supply can be routed internally via port P or externally via port X according to system requirements. This model is intended for subplate mounting and adheres to ISO porting patterns, facilitating easy integration into existing systems. Users should note that internal leakage is an inherent characteristic of this design and may increase over time. The Bosch Rexroth 4WRZ10W6-50-7X/6EG24N9EK4/D3WG152V-68 valve does not include integrated electronics OBE, meaning external control electronics are necessary for operation. This valve excels in applications where precise hydraulic flow control is critical, such as in advanced machinery and industrial automation systems.
