The 4WE6D6X/OFEW110N9DAL/62 valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic fluid to execute actuator motion in automated systems. The design follows size 6, allowing integration into NG6 manifolds, and it uses the ISO 4401-03-02-0-05 porting pattern to match common subplates. Each solenoid operates on 110 V AC at 50 or 60 Hz with a voltage tolerance of ±10%, so supply fluctuations do not impair performance. Switch-on power is 220 VA to move the spool rapidly, while holding power drops to 50 VA to reduce heating once the position is reached. Continuous operation is supported by a 100 % duty cycle, and the coil may cycle up to two times per second, giving a maximum switching frequency of 2 1/s. With two solenoids installed the valve weighs 1.95 kg, which simplifies manual handling during maintenance.
In service the valve accommodates circuit demands with a maximum flow rate of 60 l/min and withstands 350 bar on ports A, B, and P. The return line can accept up to 160 bar at port T without leakage. Electrical insulation meets class H, and the coil surface is permitted to reach 120 °C without damage. An IP65 enclosure rating protects the assembly against dust and low-pressure water jets in harsh plant environments. Switch-off overvoltage is limited to 500 V to safeguard driver electronics, and the coil is designed for the full duty stated earlier. These limits, combined with the mechanical attributes already mentioned, qualify the valve for reliable hydraulic automation where rapid, repeated direction changes are required.
