The 4WRPH6C3B40L-2X/G24Z4/M belongs to the 4WRP Solenoid Valves series from Bosch Rexroth and is used to meter flow and pressure in hydraulic automation circuits. It operates from a 24 V DC supply so it can be driven directly by common machine power buses. The coil resistance at 20 °C is 2.5 Ω, establishing the initial current draw when the coil is energized. Continuous power demand is 40 VA, which helps determine enclosure cooling requirements. Built in nominal size 6, the valve mates with NG6 subplates for compact manifold layouts. A rated flow of 40 l/min at a 70 bar differential allows stable medium-volume delivery to downstream actuators. The spool marked C3 follows a linear flow characteristic that delivers proportional metering throughout the stroke. Hysteresis stays below 0.2 percent, supporting accurate position feedback in closed-loop hydraulic controls.
The design tolerates pressures up to 315 bar on ports P, A, and B, while the T port is limited to 250 bar, making it suitable for high-pressure power units. A 100 percent duty cycle enables continuous operation without thermal cycling. The solenoid accepts up to 2.7 A, matching standard proportional amplifier modules. An IP65 enclosure protects internal components against dust and low-pressure water jets. Electrical connection is provided by a DIN 43650 plug with two power pins and a protective earth, simplifying field replacement. The body fastens to subplates that follow the ISO 4401-03-02-0-94 pattern, so interchange with other NG6 devices is straightforward. Total weight is 2.3 kg, allowing manual handling during installation.
