The 4WE6H6X/EW110N9DL directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation tasks that require electrically actuated flow control. It conforms to size 6 (NG6) dimensions, and the ISO 4401-03-02-0-05 porting pattern lines up with the NFPA D03 mounting interface to simplify stacking on standard subplates. A DL central electrical connection concentrates the coil terminals in one location for straightforward wiring. The solenoid is designed for a nominal supply of 110 V AC at 50 or 60 Hz; under these conditions it draws 0.52 A at 50 Hz and 0.39 A at 60 Hz. Continuous energization is possible because the duty cycle is 100 % ED and the winding is built to insulation class H temperature limits. During energization the inrush or switch-on power reaches 220 VA, supporting fast spool shift without overheating.
Once shifted, the holding power drops to 50 VA, reducing heat while the valve remains in its operating position. Hydraulic limits include a maximum pressure of 350 bar at ports A, B, and P, a tank port rating of 160 bar, and an allowable flow of up to 60 l/min, so the unit suits medium-pressure circuits with moderate flow demand. A concealed N9 manual override permits mechanical actuation during commissioning or power loss without exposing moving parts. The enclosure carries an IP65 protection rating, enabling installation in environments where dust and low-pressure water jets are present. These characteristics complete the technical profile and show the valve’s ability to maintain reliable directional control in continuously cycled industrial systems.
