The 4WRAE10EB60-2X/G24N9K31/A1V proportional directional valve belongs to the 4WRA Proportional Directional Valves series produced by Bosch Rexroth. It meters hydraulic flow to cylinders or motors based on an electrical command, enabling precise automation of force and velocity. The body follows the ISO 4401-05-04-0-94 porting pattern and is classified as nominal size 10, so it mounts directly on standard CETOP 05 subplates. With a 10-bar pressure drop it delivers a nominal flow of 60 l/min, and the flow can rise to 75 l/min where circuit requirements allow. Working ports a, b, and p tolerate operating pressures up to 315 bar, while the tank port is rated at 210 bar. Mineral oil of type HL or HLP to DIN 51524 is the approved pressure fluid, and it must be maintained at cleanliness class 20/18/15 according to ISO 4406 (c). FKM seals retain the fluid, and the metal housing carries IP65 protection against dust and water spray.
The valve is energized by a 24 V DC supply and interprets a ±10 V command value to modulate spool position. Each proportional solenoid can draw as much as 2.5 A, and its cold coil resistance is 2 Ω, giving a defined electrical load for the driver electronics. Connection is made through a DIN EN 175201-804 plug that combines power and control leads in one interface. System accuracy is supported by hysteresis that remains at or below 5 %, allowing repeatable flow in both actuation directions. These electrical characteristics, combined with the pressure ratings described earlier, enable the valve to integrate into servo-hydraulic loops that demand reliable response and stable current control.
