The 4WRPH6C1B40P-2X/G24Z4/M proportional solenoid valve is produced by Bosch Rexroth for the 4WRP Solenoid Valves series. It modulates hydraulic flow in automation circuits where accurate velocity and force control are required. The valve operates from a 24 V DC supply so that it can be driven directly by standard PLC outputs. A coil resistance of 2.5 Ω at 20 °C sets the current–voltage relationship and helps control heat rise. Maximum solenoid current of 2.7 A defines the usable control range, while power consumption is limited to 40 VA to reduce load on the machine power supply. The Z4 electrical connector according to DIN 43560-AM2 provides a sealed interface for wiring in harsh plant environments. A response time not exceeding 10 ms supports rapid pressure changes, and hysteresis kept below 0.2 % aids repeatable positioning when commands reverse. The non-linear P flow characteristic enables fine resolution near the neutral point for precise metering at small displacements.
The valve withstands operating pressures up to 315 bar on ports P, A, and B, enabling installation in high-pressure power units, while port T is rated for 250 bar to protect return lines against back-pressure surges. At a differential pressure of 70 bar it delivers a nominal flow of 40 l/min, allowing medium-rate cylinder or motor feeds. The ISO 4401-03-02-0-94 mounting pattern makes the body interchangeable with other size-06 subplates, and valve size 6 keeps the envelope compact while still supporting the specified flow capacity. A weight of 2.3 kg permits manual handling during maintenance without lifting equipment. NBR seals are fitted to ensure compatibility with conventional mineral-based hydraulic oils. Finally, the C1 spool symbol defines the internal land arrangement, guiding system designers on crossover leakage and control edges for their circuit diagrams.
