The 4WRA10EA30-2X/G24N9K4/V proportional directional valve is part of the 4WRA Proportional Directional Valves series produced by Bosch Rexroth to control flow and direction in hydraulic automation systems. It is built to nominal size 10 so its face dimensions align with standard manifolds, while the ISO 4401 porting pattern ensures compatibility with common subplates. Under a 10 bar differential the spool passes a nominal flow of 30 l/min, and the pressure chambers p, a, and b can operate up to 315 bar to drive cylinders or motors at high load. The solenoid is energized from a 24 V DC supply and may draw as much as 2.5 A, a value influenced by the coil resistance of 2 Ω at 20 °C that increases to 3 Ω after warm-up. A DIN EN 175301-803 (ISO 4400) plug provides the electrical interface and allows fast replacement in the field.
The valve permits a maximum flow of 75 l/min so transient peaks do not exceed the control range, and the return port T tolerates 210 bar to safeguard tank lines in pressurized circuits. Subplate mounting lets maintenance staff swap the component without disturbing pipework, reducing downtime in modular machines. An IP65 enclosure rating keeps dust and low-pressure water out of the solenoid housing, supporting reliable service on open factory floors. FKM sealing elements withstand common hydraulic oils and elevated heat, limiting leakage over long operating cycles. Coil insulation is rated for 150 °C, protecting the winding during continuous duty at high ambient temperatures. With a mass of 6.6 kg the unit can be lifted into place by one person, yet its steel body provides the rigidity needed for accurate proportional control.
