The 4WRA10W30-2X/G24K4/V proportional directional valve belongs to the 4WRA Proportional Directional Valves series and is produced by Bosch Rexroth. It meters hydraulic flow for automated motion control in machinery. With a nominal size of 10, the unit matches subplate mounting patterns for mid-range circuits. The subplate arrangement is defined by the ISO 4401-05-04-0-94 interface, ensuring interchangeability with standard manifolds. Under a pressure drop of 10 bar the spool delivers a nominal flow of 30 l/min, allowing precise actuator speed regulation. The valve withstands 315 bar on ports P, A, and B so it can be placed in high-pressure systems. Each solenoid is energized from a 24 V DC supply and draws up to 2.5 A, while a cold coil resistance of 2 Ω sets the current curve for proportional control.
Electrical connection is made through a DIN EN 175301-803 plug, and sealing to the environment reaches IP65 when the plug is fitted. The coil winding tolerates temperatures up to 150 °C, maintaining function during extended duty cycles. A maximum permissible flow of 75 l/min lets the valve handle transient peaks without spool erosion, whereas the tank port is limited to 210 bar to protect return-line components. The internal spool is marked with symbol W, indicating the flow path arrangement for centered and shifted positions. FKM seals resist mineral oils and higher temperatures, sustaining leak-tight service life. Total mass is 6.6 kg which supports rigid mounting on manifold plates.
