The 4WRPH6C3B12L-1X/G24Z4/M belongs to the 4WRP Solenoid Valves series from Bosch Rexroth and is used for proportional flow control in hydraulic automation circuits. The spool symbol C3 defines the internal flow paths for metering oil between P, A, B, and T, while size 6 keeps the mounting footprint compact for manifold blocks. A porting pattern conforming to ISO 4401-03-02-0-94 allows direct substitution with other valves that share this interface. The valve passes a nominal flow of 12 l/min at a 70 bar differential pressure to serve medium-capacity actuators, and it tolerates working pressures up to 250 bar on ports P, A, and B so it can operate in high-pressure systems. Port T also handles 250 bar, protecting the tank line from overpressure events. Dynamic behavior is supported by a maximum response time of 12 ms for a 0–100 % command step, and a maximum hysteresis of 0.5 % maintains precise positioning during repeated cycles.
Electronic operation relies on a 24 V DC supply, with overall power consumption limited to 35 VA so that cabinet power budgets are not exceeded. The solenoid coil presents a resistance of 2.5 Ω at 20 °C and draws up to 2.7 A, data that guides the drive amplifier setting for full stroke without overheating. Position feedback is energized by a transducer supply of 10 Vrms at 7 kHz and is routed through a Pg7 three-pin connector, while the solenoid windings are cabled through a DIN 43650 M16 × 1.5 connector that carries two power pins and a protective earth. An IP65 degree of protection prevents dust ingress and water jets from affecting the electronics, making the unit suitable for harsh industrial environments.
