Description

4WEH32E6X/6EW230N9K4, manufacturer material number R900928255, is a Bosch Rexroth pilot-operated directional spool valve with electrohydraulic actuation, factory size code 32, nominal size 32 and spool symbol E. The main spool controls flow direction; the pilot circuit moves the main spool.

Main-stage pressure, tank pressure and pilot pressure are independent. External pilot circuits require protection; internal pilot supply may require the specified pressure-reducing arrangement. Pressure–flow curves and minimum pilot-pressure requirements apply to the exact spool. Internal leakage is inherent to the spool design.

The mounting interface is a subplate pattern, not a threaded fluid fitting. Subplates and mounting screws are separately selected; the original pages show the applicable interfaces and installation requirements.

Representative manufacturer illustration of WH and WEH pilot-operated variants; size, spool and actuation details may differ.
