The 4WRPH6C3B25P-2X/G24Z4/M proportional valve belongs to the 4WRP Solenoid Valves series and is manufactured by Bosch Rexroth to regulate hydraulic actuators in automation circuits. It operates on a 24 VDC supply that energizes the proportional solenoid, while a coil resistance of 2.5 Ω at 20 °C defines the basic current–voltage relationship. The driver should be limited to the 2.7 A maximum solenoid current, and the connected power source must cover the 40 VA maximum power consumption. Fast closed-loop behavior is supported by a response time of no more than 10 ms for a 0–100 % command step, and position repeatability is maintained by hysteresis held to 0.2 % or lower. When set to its rated conditions the valve passes a nominal flow of 25 l/min, providing sufficient throughput for medium-size cylinders and motors.
With a size classification of NG6, the valve bolts to an ISO 4401-03-02-0-94 subplate, and the C3 spool symbol defines the internal port configuration used by the control algorithm. The P non-linear flow characteristic shapes the metering curve so the controller can fine-tune low-speed motion. Ports p, a, and b withstand operating pressures up to 315 bar, while the return port t is limited to 250 bar to match common tank lines. An IP65 degree of protection keeps dust and low-pressure water from reaching the electrical parts in typical machinery environments. The integrated position transducer provides a ±10 V feedback signal that closes the loop for directional accuracy, and the overall weight of 2.3 kg allows direct manifold support without additional brackets.
