The 4WRAE6E07-2X/G24K31/A1V proportional directional valve belongs to the 4WRA Proportional Directional Valves series from Bosch Rexroth and serves to modulate flow and direction in hydraulic automation systems. It is built in size 6 (NG6) format, making it suitable for installations that favor compact subplates. The subplate interface follows porting pattern ISO 4401-03-02-0-05 so the valve can be dropped into standard manifolds without adapter blocks. A nominal supply of 24 VDC powers the integrated electronics. Position commands are accepted as ±10 V, allowing direct connection to most industrial controllers, and the input resistance is greater than 100 kΩ to minimize load on the driving source. During full stroke the solenoid draws up to 1.2 A, resulting in a maximum electrical demand of 24 VA. Residual ripple is limited to 2.5 Vpp so spool movement remains steady under fluctuating supply conditions.
The metering section is rated for 350 bar on ports A, B, and P, while the tank port withstands 210 bar, enabling operation in high-pressure circuits. With hydraulic media at these pressures the valve passes a nominal flow of 7 l/min and can reach up to 42 l/min when fully actuated. Sealing elements are made from FKM to tolerate common mineral oils and higher temperature service. Ingress protection reaches IP65 when the electrical connector is installed, defending the coil against dust and low-pressure jets. Internal passages are built to cleanliness class 20/18/15 per ISO 4406, specifying the particle limits required for reliable operation. Total mass is 2.5 kg, allowing one-person handling during installation.
