The 4WRPH6C3B12L-2X/G24Z4/M proportional valve belongs to the 4WRP Solenoid Valves series manufactured by Bosch Rexroth for precise hydraulic automation. It fits the NG6 nominal size and follows the ISO 4401-03-02-0-94 mounting pattern, making it compatible with standardized subplates. A spool coded C3 meters the flow to achieve a nominal rate of 12 l/min, while the P, A, and B ports withstand pressures up to 315 bar and the T port up to 250 bar. Electrical performance is defined by a coil resistance of 2.5 Ω at 20 °C and a continuous duty cycle of 100 %, allowing sustained operation without overheating.
The valve is powered from a 24 V DC supply, and the solenoid draws up to 40 VA with a peak current of 2.7 A. Wiring is handled by a DIN 43650 connector that provides two power pins and a protective earth, while a Pg7 four-pin socket carries the integrated position transducer output of ±10 V for closed-loop control. An IP65 enclosure rating protects the unit against dust and water jets, and the assembled weight is 2.3 kg for easy manifold mounting. These electrical interfaces and environmental protections complement the hydraulic capabilities listed earlier, supporting reliable service in automated presses, molding machines, and other motion-control systems.
