4WRP6EA08S-1X/G24Z4/M-755

The 4WRP6EA08S-1X/G24Z4/M-755 valve belongs to the 4WRP Solenoid Valves series and is produced by Bosch Rexroth for closed-loop hydraulic automation where proportional control of actuator speed and force is required. It fits the NG6 interface, so it installs on compact manifolds without adapters, and its ISO 4401-03-02-0-94 mounting pattern keeps port geometry consistent across suppliers. A nominal flow of 8 l/min at a 10 bar differential lets the unit meter oil in small servo loops, while the progressive flow characteristic allows fine adjustment at low command signals and stable increase toward full stroke. Metering is achieved through a triangular notch that limits turbulence and supports smooth velocity profiles. Circuit feedback is provided by an AC/AC LVDT mounted on the A-side, enabling the drive electronics to center the spool quickly. The valve withstands 315 bar on the pressure, A, and B ports to suit medium-pressure systems, and its tank port tolerates up to 250 bar so return lines can accept transient pressure peaks without damage.

Electrical data match typical machine supply panels; the integrated amplifier runs from a 24 V DC source, and total power consumption does not exceed 40 VA, allowing connection to standard control cabinet supplies. A maximum solenoid current of 2.7 A and a coil resistance of 3 Ω at 20 °C define the driver settings necessary for full spool travel without overheating. The valve uses a DIN 43650/ISO 4400 connector with an M16 × 1.5 thread, which simplifies wiring and supports quick replacement. An IP65 degree of protection guards the housing against dust and water jets so the device can be mounted near wet process areas. NBR seals are fitted to maintain compatibility with conventional mineral oils and to preserve leakage integrity across the service life. With an assembled weight of 2.8 kg, the component can be handled by a single technician during installation and maintenance.
