4WREE10W2-75-2X/G24K31/A1V

The 4WREE10W2-75-2X/G24K31/A1V proportional directional valve belongs to the 4WRE Proportional Directional Valves series and is manufactured by Bosch Rexroth. It meters oil flow in closed-loop hydraulic automation systems, providing position-controlled spool movement via integrated electronics. With a rated flow of 75 l/min at a differential pressure of 10 bar, the valve can accurately position actuators at medium flow rates. A maximum operating pressure of 315 bar on ports A, B, and P allows use in high-pressure circuits common in presses and molding machines. The electromagnetic coil shows a cold resistance of 4.55 Ω, ensuring predictable current draw for proportional control, and it can operate up to 150 °C before thermal limits are reached. Electrical connection is made through a DIN EN 175201-804 connector, and an IP65 housing protects the internal components against dust and low-pressure water jets in typical industrial environments.

During sustained duty the coil resistance rises to 6.82 Ω, a value that stabilizes current and prevents overheating when the valve remains energized for long cycles. The T return port tolerates pressures up to 210 bar, so the unit can be installed in systems where back-pressure develops during rapid actuator deceleration. For applications demanding higher throughput, the manufacturer recommends a maximum flow of 180 l/min, which maintains stable spool positioning without excessive pressure drop. Fluoroelastomer (FKM) seals are used to resist mineral oils and many synthetic fluids, extending service life in harsh chemical conditions. The assembly weighs 6.5 kg, a factor to consider when mounting the valve on manifolds or mobile machine frames.
