The 4WRPH10C1B50P-2X/G24Z4/M valve belongs to the 4WRP Solenoid Valves series from Bosch Rexroth and is installed in hydraulic automation circuits to meter flow proportionally to a control signal. Its nominal size is 10, giving passage dimensions suitable for medium-frame manifolds, while a nominal flow of 50 l/min at a 70 bar differential supports rapid cylinder or motor movement. The pressure limits reach 315 bar on ports P, A, and B and 250 bar on the tank port, permitting high-duty service with adequate return-line safety. Electrical excitation is provided by a 24 V DC supply; the solenoid draws up to 3.7 A through a coil whose resistance is 2.4 Ω at 20 °C, resulting in a power demand of 60 VA that must be accommodated by the drive electronics.
Continuous duty operation is possible because the valve is rated for a 100 % duty cycle, so temperature rise does not restrict actuation frequency. An IP65 degree of protection shields the enclosure against dust and water jets, allowing use in exposed machine compartments. The mounting interface follows ISO 4401-05-04-0-94, enabling direct stack assembly without custom subplates, and electrical termination is handled by a DIN 43650 connector with an M16 × 1.5 thread for secure cable glands. NBR seals are fitted to resist common hydraulic oils and to contain pressure at the spool lands. Integrated electronics provide a ±10 V transducer output and accept a ±15 V supply, simplifying feedback to the motion controller. The assembled unit weighs 6.8 kg, which guides handling and support structure design.
