The 4WEH32J6X/6EW110N9K4 valve is produced by Bosch Rexroth within the WEH Directional Spool Valves series and serves to switch hydraulic flow paths in automated machinery. The unit is built as a 4/3-way configuration, providing two service positions and a centered neutral state. Its spool follows symbol J, defining the internal bridge arrangement used in each position. A nominal size of NG32 allows passage of large oil volumes, and the valve supports up to 680 l/min when system pressure reaches 350 bar. Port interfaces comply with ISO 4401-10-09-0-05 so the body fits standard subplates without adaptation.
Clean operation demands fluid cleanliness of ISO 4406 (c) 20/18/15 to protect the sliding spool and prolong service life. Electrical actuation is provided through a DIN EN 175301-803 K4 connector that mates with common industrial cable glands. A concealed manual override labeled N9 lets technicians shift the spool locally during commissioning or in case of power loss. The pilot stage tolerates pressures up to 250 bar and requires at least 8.5 bar to recenter the spring-loaded spool. In three-position form the pilot volume is 29.4 cm³, influencing response time and damping. Installation uses six M20 × 80 mounting screws, and the assembly with two solenoids weighs 41.0 kg.
