The 4WE6D6X/OFEG24N9DK25L directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and switches hydraulic flow paths in automated machinery. With a nominal size of 6, the valve fits NG6 manifolds where space is limited. Its mounting pattern matches ISO 4401-03-02-0-05 so installers can bolt it to standard subplates without adapter blocks. The wet-pin solenoid design allows the coil to run in hydraulic oil for better cooling and a longer service life. Electrical connection is made through a DK25L five-pole plug, which provides secure wiring for control signals and power. The coil is rated for 24 V DC so it can tie directly into common machine control buses, and it draws 1.25 A during operation, defining conductor sizing and fuse selection. Continuous energization is permitted because the coil dissipates only 30 W at that rating, and the 100 % duty cycle prevents overheating during prolonged actuations.
The hydraulic side parameters are set to match high-pressure circuits: the valve carries a maximum operating pressure of 350 bar on the P, A, and B ports and accepts up to 210 bar on the T port when used with direct current coils, enabling use in heavy-duty loops while protecting the return line. Flow capacity reaches 80 l/min, permitting rapid cylinder or motor movement within the NG6 envelope. A concealed N9 manual override lets maintenance staff shift the spool locally without energizing the solenoid, while the OF detent holds the spool in its last position after power is removed for fail-safe logic. To preserve performance, the hydraulic fluid must meet ISO 4406 cleanliness level 20/18/15, limiting particle-induced wear. The housing meets IP65 so dust and water spray cannot enter the electrical cavity. Two installed solenoids bring the assembly weight to 1.95 kg, facilitating easy handling during manifold changes.
