The 4WE6D6X/OFEW110N9K4/B10V directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and routes pressurized fluid between service lines in automated hydraulic systems. Its solenoid operates on a nominal 110 V AC supply at 50/60 Hz, and the coil accepts a ±10 % voltage window to cope with mains variation. Initial switch-on requires 220 VA, after which power falls to 50 VA to hold the spool with reduced heating. Continuous energization is possible because the design is rated for a 100 % duty cycle, while a 500 V switch-off overvoltage ceiling safeguards insulation. Connection is provided by a K4 plug that follows DIN EN 175301-803, and the enclosure carries an IP65 rating to block dust ingress and low-pressure water.
The valve handles flow rates to 60 l/min, and pressure ports a, b, and p tolerate 350 bar, allowing installation in high-pressure circuits; the tank port is limited to 160 bar. A throttle insert with a 1.0 mm orifice in port P moderates inrush flow to improve stability. Mounting follows the ISO 4401-03-02-0-05 sub-plate pattern so the component fits standard CETOP 3 manifolds without adapter plates. A concealed manual override marked N9 lets maintenance personnel shift the spool when electrical power is not available. FKM seal material withstands elevated temperatures and chemically aggressive fluids encountered in modern hydraulic oils, and the assembly weight of 1.95 kg with both solenoids attached simplifies handling during installation.
