4WRA10E60-2X/G24N9K4/V

The 4WRA10E60-2X/G24N9K4/V proportional directional valve, manufactured by Bosch Rexroth for the 4WRA Proportional Directional Valves series, regulates flow and switches direction in hydraulic automation circuits. Its nominal size of 10 defines the port geometry, letting the body fit compact manifolds without custom machining. The ISO 4401-05-04-0-94 mounting pattern matches common subplates so exchange or service work can be performed rapidly. A spool with symbol E sets the internal land arrangement that proportionally meters fluid between pressure, actuator, and tank lines. The valve delivers a nominal flow of 60 l/min at a 10 bar pressure drop, giving predictable response for servo loop tuning, while a permissible flow ceiling of 75 l/min provides additional capacity for transient peaks. Ports P, A, and B withstand operating pressures up to 315 bar, enabling use in high-force cylinders, whereas the T port is limited to 210 bar to protect return lines and reservoir components.

The electromagnetic section is driven from a 24 V DC supply, and each solenoid draws up to 2.5 A, a value set by a coil resistance of 2 Ω measured at 20 °C. Continuous energization is possible because the duty cycle is 100 %, and windings may rise to a maximum temperature of 150 °C without loss of function. Environmental sealing reaches IP65, so the enclosure resists dust ingress and water jets when the electrical connector compliant with DIN EN 175301-803 is fully tightened. Fluorocarbon FKM seals prevent leakage and tolerate common hydraulic oils as well as higher fluid temperatures. The assembled valve weighs 6.6 kg, light enough for direct mounting on mobile machinery yet robust for fixed industrial manifolds. The thermal rating together with the full duty specification lets the unit stay actuated during long positioning cycles without external cooling or dwell periods, supporting uninterrupted machine operation on production lines.
