The 4WE6D9-6X/OFEW110N9DK25L/N12 directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic automation tasks that require compact flow switching. With a nominal size of 6, it fits manifolds that conform to the ISO 4401-03-02-0-05 porting pattern. Two spool positions allow the circuit to alternate between distinct flow paths, and the absence of a spring return together with a detent keeps the spool locked in its last commanded state. A concealed manual override provides local actuation when electrical power is unavailable. Flow through ports a and b is metered by a 1.2 mm throttle insert, while system reliability is supported by a required oil cleanliness class of ISO 4406 20/18/15.
The solenoid coil is designed for a nominal supply of 110 V AC at either 50 Hz or 60 Hz, drawing 0.52 A at 50 Hz and 0.39 A at 60 Hz; a ±10 % voltage tolerance ensures stable performance on typical industrial mains. Continuous energization is permitted thanks to a 100 % ED duty rating, and wiring is completed through a DK25L five-pole connector that includes an LED for coil status indication. The valve passes up to 60 l/min without exceeding its flow rating, handles 350 bar on pressure and work ports, and withstands 160 bar on the tank port.
