The 4WRPH6C4B25P-2X/G24Z4/M valve belongs to the 4WRP Solenoid Valves series produced by Bosch Rexroth for hydraulic automation tasks that require proportional flow control. It is supplied in nominal size 6 and attaches to a manifold with the ISO 4401-03-02-0-94 mounting pattern. A nominal flow of 25 l/min at 35 bar Δp per notch is delivered through a P-type non-linear characteristic provided by the C4 spool. Step changes reach full stroke in no more than 10 ms, and hysteresis is held to 0.2 percent, supporting accurate actuator positioning. The housing meets IP65 for ingress protection, and the overall weight is 2.3 kg, allowing easy handling during installation.
The integrated amplifier operates from a 24 V DC supply and drives a coil with 2.5 Ω resistance at 20 °C, permitting a peak solenoid current of 2.7 A while capping power consumption at 40 VA. Process ports p, a, and b tolerate working pressures up to 315 bar, whereas the tank port t is limited to 250 bar to safeguard return lines. A position transducer is mounted on side B, providing direct feedback for closed-loop control. These electrical and hydraulic limits combine to deliver stable flow modulation across demanding industrial duty cycles.
