The 4WRPH6C3B24L-2X/G24K0/M-750 belongs to the 4WRP Solenoid Valves series and is manufactured by Bosch Rexroth for proportional control tasks in hydraulic automation. It operates on a 24 V DC supply, and the coil resistance of 2.5 Ω at 20 °C defines the initial current required for actuation. A maximum solenoid current of 2.7 A sets the upper limit for the driver electronics, while the 40 VA power rating helps size power supplies. Continuous service is possible because the duty cycle is 100 % ED, preventing overheating during long cycles. Connection is made through a central 7-pin plug, allowing quick wiring in control cabinets. A linear flow characteristic lets the valve deliver proportional output as coil current changes, and it mounts to subplates that follow the ISO 4401-03-02-0-94 pattern for interchangeability with other size-6 devices.
The unit handles operating pressures up to 315 bar at ports P, A, and B, enabling use in high-pressure circuits, while the tank port is limited to 250 bar to protect return lines. A maximum flow of 40 l/min defines the ceiling for throughput, and a nominal flow of 24 l/min at a 70 bar differential offers a reference point for sizing pumps and actuators. Fluid entering the valve must meet ISO 4406 cleanliness class 18/16/13 to avoid spool wear and sticking. The valve withstands mechanical shocks of 40 g, so it remains functional in mobile or vibration-prone machinery. Its weight of 2.3 kg aids manual installation without lifting equipment, and the nominal size 6 porting keeps the envelope compact for dense manifold layouts.
