4WRPH6C4B15P-2X/G24K0/M-750

The 4WRPH6C4B15P-2X/G24K0/M-750 valve is manufactured by Bosch Rexroth in the 4WRP Solenoid Valves series. It serves as a proportional spool valve for hydraulic automation, modulating flow to actuators in closed loop systems. The valve is built to nominal size 6 so it mounts on compact subplates without excessive manifold area. A porting pattern conforming to ISO 4401-03-02-0-94 aligns the P, A, B, and T passages with standard industrial blocks and reduces installation work. Nominal flow is rated at 15 l/min when the pressure drop across the valve reaches 70 bar, allowing accurate metering in medium-power circuits. Its non-linear P flow characteristic provides sensitive response around the neutral position for precise positioning tasks. The C4 spool symbol defines overlap geometry that balances leakage and control resolution. Electrical drive is achieved from a 24 V DC supply; the coil shows 2.5 Ω resistance at 20 °C, draws up to 2.7 A, and limits input power to 40 VA for cabinet sizing.

Maximum operating pressure on the P, A, and B ports is 315 bar, while the T port is limited to 250 bar, enabling the valve to handle high-pressure supply lines yet protect the tank return path. An IP65 protection class keeps dust ingress and low-pressure water jets away from the solenoid housing in typical machine environments. NBR seals are installed to maintain fluid compatibility with standard mineral oils and to sustain service temperatures without hardening. Mechanical durability is enhanced by tolerance of shocks up to 40 g, making the device suitable for mobile frames or presses subject to vibration. For position feedback, an internal transducer delivers a ±10 V output that interfaces directly with motion controllers. The unit relies on an external amplifier as its trigger electronics, giving designers freedom to select control cards with the required dither and ramp functions. These hydraulic and electrical limits combine to support reliable proportional flow control across a wide range of automated machines.
