The 4WE6D6X/OFEW110NK4 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic oil between pressure and service lines in automated machinery. The unit is built to size 6, carries two solenoids to shift the spool, and offers two discrete spool positions arranged according to symbol D. A maximum operating pressure of 350 bar on ports P, A, and B combines with a peak flow capacity of 60 l/min to handle medium-duty circuits that require fast response. Each solenoid is supplied with 110 V AC at 50 or 60 Hz, and the design tolerates voltage variations of ±10 %, maintaining reliable performance under fluctuating mains conditions. During initial energization the coil draws 220 VA, providing the magnetic force needed for immediate spool movement.
The valve sustains energized states with a holding demand limited to 50 VA, and a 100 % ED duty rating allows continuous activation without mandatory cooling periods. Coil surface temperature can climb to 120 °C while remaining within safe limits. Tank port T is protected by a 160 bar pressure ceiling to control back-pressure in return lines. A detent coded OF locks the spool mechanically when power is removed, preserving circuit state. Electrical hookup is completed through a K4 connector that follows DIN EN 175301-803, simplifying field wiring. Overall weight is 1.95 kg, enabling straightforward mounting on sub-plates or manifolds.
