4WE6L6X/EW110N9DK25L/62

The 4WE6L6X/EW110N9DK25L/62 directional spool valve is built by Bosch Rexroth for the WE Directional Spool Valves series. Designed to shift hydraulic flow to actuators and return lines in automated machinery, it fits subplate cavities defined by nominal size 6. The porting pattern follows ISO 4401-03-02-0-05, so it aligns with standard CETOP 03 manifolds in modular circuits. A maximum operating pressure of 350 bar at ports p, a, and b allows the valve to handle high-pressure supply lines, while the tank port withstands up to 160 bar to prevent case drain damage in back-pressure conditions. The assembly supports a maximum flow of 60 l/min, enabling medium-speed cylinder or motor cycles without excessive pressure drop. IP65 ingress protection keeps the solenoid enclosure sealed against dust and water jets during wash-down or outdoor service. Hydraulic oil entering the valve should meet ISO 4406 cleanliness class 20/18/15 to maintain spool clearance and prevent sticking. An inrush requirement of 220 VA ensures the solenoid develops the magnetic force needed for rapid spool shift at startup.

The solenoid coil is wound for 110 V AC at 50 or 60 Hz, letting one model serve plants that share either mains frequency. Under steady energization, the current draws are 0.52 A at 50 Hz and 0.39 A at 60 Hz, values that match common control transformers. Holding power is limited to 50 VA, which reduces coil temperature during extended shifts, and the duty cycle is 100 % ED so the valve may stay energized without pause. Voltage tolerance of ±10 % allows the spool to shift reliably even when supply lines sag or rise within that band. Electrical connection is achieved through a 5-pole ANSI/B93.55M plug, giving separate terminals for power and protective ground in a single molded housing. A concealed manual override permits safe local actuation when commissioning or troubleshooting without exposing moving parts.
