Bosch Rexroth 4WRZ25E1-220-70 6EG24N9K4 D3V Directional Control Valve

Bosch Rexroth 4WRZ25E1-220-70 is a pilot-operated proportional directional valve that delivers precise, current-controlled flow in hydraulic systems. It belongs to the 4WRZ family and uses a detachable-coil proportional solenoid (6EG24N9K4) to move the internal spool, enabling smooth, variable control of actuators such as cylinders and hydraulic motors. The D3V variant code identifies the specific spool/valve configuration, while the E1-220-70 suffix places it in the component-series 70–79 electrical family. Catalog references for this exact configuration include Bosch Rexroth part numbers like R900964717, and multiple distributors list the model with the same footprint and electrical characteristics. Typical applications span industrial automation, machine tools, presses, and heavy equipment where repeatable directional control and proportional flow are required. The 4WRZ platform is designed to integrate proportional solenoids with pilot-operated hydraulics to meet precise actuation needs in demanding environments.
