The 4WRPH10C4B50L-2X/G24Z4/M valve is manufactured by Bosch Rexroth for the 4WRP Solenoid Valves series and regulates flow and pressure in hydraulic automation loops. Its nominal size of 10 sets the port dimensions for medium flow circuits, and the ISO 4401-05-04-0-94 mounting interface allows direct installation on standard manifolds. A C4 spool symbol identifies the internal land geometry used for directional metering, while the linear flow characteristic ensures proportional flow as the spool shifts. Under a 70 bar pressure drop the valve passes a nominal flow of 50 l/min, matching common actuator rates. Ports P, A, and B withstand up to 315 bar, whereas port T is limited to 250 bar to suit return line conditions. A 24 V DC supply energizes the proportional solenoid that drives the spool.
The solenoid draws a maximum current of 3.7 A, so the driver electronics must be sized accordingly, and electrical load reaches 60 VA to define panel power allocation. Coil resistance is 2.4 Ω at 20 °C, providing a reference for temperature compensation, while the integrated position transducer outputs a ±10 V signal that closes the control loop. A Pg7 four-pin connector is provided for the transducer to secure feedback wiring, and power leads attach through a DIN 43650 connector with an M16 × 1.5 thread to maintain reliable contact. An IP65 protection class keeps dust and low-pressure water jets from entering the housing, and the valve weighs 6.8 kg, influencing mounting bracket selection.
