The 4WE6D6X/OFEW110N9DK25L/V/62SO43A-1750 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series and serves to route pressurized fluid in hydraulic automation circuits. The solenoid assembly is designed for a nominal supply of 110 V AC at 50/60 Hz, so it can be wired directly to standard control transformers. Current demand is 0.52 A at 50 Hz and 0.39 A at 60 Hz, giving predictable load values for protective devices. Switch-on power reaches 220 VA, after which holding power falls to 50 VA to limit heat generation. A 100 % duty cycle allows the valve to remain energized continuously without enforced rest periods. Windings meet insulation class H, and coil surface temperature may reach 120 °C while staying within that thermal category. With two solenoids the unit weighs 1.95 kg, which eases handling during manifold or sub-plate installation.
The hydraulic section supports a maximum flow of 60 l/min, establishing the upper throughput for connected pumps and actuators. Operating pressure is permitted up to 350 bar on ports P, A, and B, whereas the T port is limited to 160 bar to protect return lines. The valve functions with hydraulic fluid temperatures up to 80 °C and ambient conditions up to 50 °C when equipped with FKM seals, maintaining stable performance in warm environments. It accepts viscosities as high as 500 mm²/s, allowing use with a broad viscosity range of mineral oils. System cleanliness must be kept to ISO 4406 class 20/18/15 so the spool can shift without abrasion or blockage. Together these ratings define the operating envelope needed for reliable switching duty in automated hydraulic machinery.
