The 4WE6D6X/OFEG24N9K4KSO21 directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic automation circuits. The valve is built in size 6 and mounts on subplates matching the ISO 4401-03-02-0-05 interface, allowing quick exchange in compact manifolds. A detent spool return labeled OF holds the spool in its last actuated position without continual solenoid power, while a concealed manual override coded N9 permits local actuation when electrical control is unavailable. Hydraulic channels p, a, and b withstand operating pressures up to 350 bar, whereas the t port is limited to 210 bar. The design supports a maximum flow of 80 l/min and requires fluid cleanliness conforming to ISO 4406 class 20/18/15. Total mass with two solenoids is 1.95 kg.
The electromagnetic section uses 24 V DC coils that draw a rated current of 1.25 A, producing 30 W of nominal power for consistent spool movement. Continuous service is allowed because the duty cycle is specified at 100 % ED, eliminating the need for cooling pauses during extended machine cycles. Switching commands reach up to 4.2 operations per second, giving responsive control in fast logic sequences. Electrical connection is achieved through a DIN EN 175301-803 type K4 plug, and the housing seals to an IP65 protection level to resist dust and water spray in industrial environments. Together these electrical features complement the hydraulic limits described earlier, forming a valve suited for precise, repeatable actuation in automated pressure and flow control assemblies.
