The 4WE6MA6X/EW110N9DK25L/B10V valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is used to shift hydraulic flow paths in automated circuits. It is built in nominal size 6, which sets the port spacing for subplates and manifolds. A maximum operating pressure of 350 bar allows the unit to control high-pressure lines, while a rated flow of 60 l/min determines the volume it can direct without excessive pressure drop. The M-coded spool governs the internal flow pattern selected by the machine designer. An energized solenoid requires 110 V at 50/60 Hz, and the ±10 % voltage tolerance maintains reliable switching under supply fluctuations. Initial pull-in needs 220 VA of switch-on power, after which consumption falls to 50 VA holding power to limit heat rise. The coil can remain powered continuously thanks to a 100 % ED (S1) duty cycle rating.
The valve must receive oil filtered to ISO 4406 20/18/15 cleanliness so the spool and seals are not damaged by particles. It mounts on subplates that follow the ISO 4401-03-02-0-05 pattern, also known as NFPA D03, streamlining interchangeability in manifold blocks. Electrical hookup is made through a DK25L five-pole Mini-Change connector, and a concealed N9 manual override lets technicians shift the spool locally during setup or in the event of power loss. The return line may be pressurized up to 160 bar at port t without risking seal extrusion. All dynamic seals are manufactured from FKM to withstand high-temperature hydraulic fluids. A 1.0 mm throttle insert in port P, identified by code B10, creates a fixed orifice that dampens pressure surges when the spool changes state.
