The 4WE6D6X/EW110N9DK23L/62SO43A-1707 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It shifts hydraulic flow paths to automate cylinders and motors in machinery. The solenoid is wound for 110 VAC, so it can be driven directly from standard plant power, and the ±10 % voltage tolerance keeps actuation consistent when supply fluctuates. At energization the coil draws 220 VA to establish the magnetic field that moves the spool, while once the stroke is completed the holding demand falls to 50 VA to cut heat and energy use. Continuous duty is possible because the coil is rated for 100 % S1 operation and carries insulation class H to withstand elevated winding temperature. Electrical hookup is made through a DK23L three-pole connector, and the housing is sealed to IP65 which blocks dust and low-pressure water jets. A concealed N9 manual override lets maintenance staff shift the spool locally without exposing delicate parts.
The valve body is built to nominal size 6, giving passage diameters that limit pressure loss while keeping the envelope compact for tight manifold stacks. It bolts onto an ISO 4401-03-02-0-05 interface, and the port layout also follows the NFPA D03 pattern so adapters are unnecessary on standard subplates. A locating hole equipped with a locking pin, identified by the /62 code, centers the body during installation and prevents rotation under load. Maximum service flow is 60 l/min, supporting medium-capacity actuators, while pressure limits of 350 bar on ports P, A, and B permit use in high-pressure circuits; port T is capped at 160 bar to safeguard return plumbing. These hydraulic figures are achieved without auxiliary cooling because the spool and body clearances manage internal leakage and thermal expansion within tolerances.
