Bosch Rexroth 4WREE6W1-08-3X/V/24F1 proportional directional valve

4WREE6W1-08-3X/V/24F1, material number R901496449, is a factory-listed size 6 direct-operated proportional directional valve with electrical position feedback and integrated electronics. The W1- spool execution has 8 L/min nominal flow at a valve pressure differential of 10 bar, equivalent to 5 bar per control edge. Its F1 interface accepts a 4–20 mA current command and uses 24 VDC nominal supply. FKM seals require compatibility with the selected hydraulic fluid.

The applicable series limits distinguish 350 bar at P, A and B from 210 bar at T. Internal leakage is inherent to the design; de-energized mechanical centering must not be interpreted as leak-free isolation. The tank line must not run empty. The manufacturer’s characteristic tests use HLP46 at 40 ±5 °C, and the permissible operating envelope remains flow- and pressure-dependent. Mating connectors, subplates and mounting hardware are separate-order accessories.

The asymmetric spool provides full nominal flow at P→A and A→T and half nominal flow at B→T and P→B under the specified conditions. Standard symmetric-spool curve panels do not establish an exact asymmetric-execution flow envelope.
