The part number 4WE6D6X/OFEW110N9DK25L/62SO43A-1750 is a directional spool valve from the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation where circuits need reliable on-off control. It mounts on an NG6 manifold because its nominal size is 6, and it follows the ISO 4401-03-02-0-05 porting pattern to align with standardized subplates. The unit tolerates up to 350 bar on pressure, A, and B ports, allowing it to work in high-pressure systems, and it passes flows up to 60 l/min, fitting medium-capacity actuators. A duty cycle of 100 % ED permits the solenoid to remain energized without cooling breaks. The coil runs on 110 V AC at 50/60 Hz; start-up demands 220 VA of switch-on power, while continuous operation draws 0.52 A at 50 Hz, simplifying thermal and fuse calculations.
Electrical termination is handled by a DK25L five-pole light connector, which provides quick disconnect capability in control cabinets rated IP65, matching the valve’s own protection class against dust and water spray. The winding is built to insulation class H so it withstands elevated temperatures during prolonged duty, and once the spool has shifted it holds position with only 50 VA of holding power to reduce energy use. A concealed manual override labeled N9 lets technicians shift the valve locally; the override should be used only when tank pressure is below 50 bar to prevent backflow. Return port design supports up to 160 bar, accommodating installations with significant back-pressure. On 60 Hz supplies the coil draws 0.39 A, trimming heat generation compared with 50 Hz operation. These features enable consistent electrical and hydraulic performance within the envelope defined for the WE series.
