The 4WRPH6C3B24L-2X/G24Z4/M-561 valve is produced by Bosch Rexroth as part of the 4WRP Solenoid Valves series and is intended to modulate hydraulic flow and pressure in automated machinery. With a nominal size of 6, the body fits compact manifolds for medium flow rates, and the mounting surface follows ISO 4401-03-02-0-94 so it can be installed on standard subplates. The solenoid is energized by a 24 V DC supply and consumes 40 VA, while its copper winding shows a resistance of 2.5 Ω at 20 °C, which defines current draw. Continuous operation is supported by a 100 % duty cycle, and the drive electronics must not exceed the 2.7 A maximum solenoid current. Electrical hookup uses a DIN 43650 / ISO 4400 two-pole plus earth connector, allowing quick field service.
The valve delivers a nominal flow of 24 l/min at a 70 bar pressure drop, and the linear flow characteristic provides proportional output for closed-loop control. Stroke movement completes within 10 ms from 0 to 100 %, giving rapid response in servo axes. An internal position sensor operates from a ±15 V, 35 mA supply so feedback circuits remain lightly loaded. Ports P, A, and B tolerate pressures up to 315 bar, while port T is limited to 250 bar to protect return lines. The enclosure achieves IP65 when the mating connector is fitted, shielding the coil from dust and water jets. All dynamic seals are made from NBR to maintain compatibility with common mineral hydraulic oils.
