The 4WRAE10W1-30-2X/G24N9K31/A1V valve is produced by Bosch Rexroth and belongs to the 4WRA Proportional Directional Valves series, where it controls flow and direction in hydraulic automation circuits. With a nominal size of 10, it suits manifolds designed for medium line diameters. The ISO 4401-05-04-0-94 mounting pattern allows direct installation on standardized subplates, reducing piping. Under commanded conditions, the valve delivers a rated flow of 30 l/min, while a fully opened spool passes up to 75 l/min for peak demand. Electronic actuation is powered by a 24 VDC supply, and the ±10 V command value input accepts proportional signals for precise spool positioning. Each solenoid may draw up to 2.5 A, and the coil shows 2 Ω resistance at 20 °C, enabling accurate power-supply sizing.
System pressure on ports A, B, and P can reach 315 bar, so the unit fits high-pressure circuits. The tank port tolerates 210 bar, allowing controlled back-pressure operation. An IP65 protection class shields the housing against dust and water jets. Continuous duty is possible because the coil insulation withstands 150 °C. Oil cleanliness should be held at ISO 4406 code 20/18/15 to protect the metering edges. Electrical connection is via a DIN EN 175201-804 K31 plug, simplifying coil replacement. FKM seals tolerate synthetic or high-temperature fluids. The assembled unit weighs 6.8 kg, which influences manifold support and handling devices.
