The 4WE6H6X/EW110N9DK25L/62 directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth. It directs hydraulic flow in automated machinery by energizing an AC solenoid built for a nominal 110 V supply at 50 or 60 Hz. The solenoid accepts a ±10 percent voltage fluctuation so line variations do not interrupt switching. A switch-on power demand of 220 VA produces the initial magnetic force needed to shift the spool. After movement, the circuit draws 50 VA holding power to maintain position while limiting heat rise. Continuous operation is possible because the coil is rated for a 100 percent duty cycle under S1 classification. Class H insulation supports this rating, and the winding can reach a surface temperature up to 120 °C without damage. Electrical connection is provided through a five-pole DK25L plug, simplifying removal and replacement.
The hydraulic section carries up to 60 l/min of oil, matching medium-flow actuators in industrial presses and tooling lines. Ports P, A, and B withstand 350 bar so the valve can manage high-pressure supply circuits. The tank port endures 160 bar, allowing back-pressure from return lines without leakage. Spool repositioning can repeat at two cycles per second, providing adequate response for standard directional control loops. External sealing and screw joints meet IP65, allowing installation in wash-down or dusty zones. Mounting follows the ISO 4401-03-02-0-05 pattern, equivalent to NFPA D03, which aligns the valve with common sub-plates. A concealed N9 manual override lets maintenance staff shift the spool mechanically when power is absent. Alignment on the manifold is assisted by an ISO 8752-3x8-St locating pin provided in the /62 variant.
