Bosch Rexroth R901273376 Hydraulic Proportional Valve

Bosch Rexroth R901273376 is a hydraulic proportional directional valve from the 4WRKE25 family, delivering electronically controlled flow and direction for precise actuator control. This variant—4WRKE25 E1-220L-3X/6EG24K31/F1D3V—signals an external pilot oil supply configuration (E1-220L-3X) and uses the F1D3V coil assembly with the 6EG24K31 electrical interface to drive the proportional solenoid. Designed for Rexroth-compatible hydraulic circuits, it converts an electrical input into a proportional hydraulic output to modulate valves that control cylinders or hydraulic motors. Typical applications include automation systems, machine tools, and presses where accurate speed and position control of actuators are required. The R901273376 designation identifies a Rexroth part intended for integration with compatible drive electronics and external pilot configurations, delivering repeatable proportional performance within the brand’s valve lineup. This model is suited to installations that rely on a precise, adjustable control signal to regulate actuator movement and hydraulic flow.
