The 4WE6H6X/EW110N9DL/V directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It shifts hydraulic flow paths by means of two solenoids that are energized by a 110 V AC coil at 50 or 60 Hz. The switch-on power is 220 VA, providing the magnetic force required to overcome spring preload and move the spool, while the holding power falls to 50 VA to minimize heat once the position is reached. Continuous energization is permitted because the coil is rated for a 100 % ED duty cycle, and the insulation system is classified as class H to tolerate winding temperatures during long runs. Under those conditions the coil surface may reach 120 °C, so the IP65 enclosure prevents dust ingress and low pressure water jets from contacting live components. When fed from a 110 V, 50 Hz source the solenoid draws 0.34 A, and at 60 Hz the current rises to 0.39 A. With both solenoids fitted the valve weighs 1.95 kg, enabling direct manifold mounting without additional support.
The hydraulic end of the 4WE6H6X/EW110N9DL/V accommodates system pressures up to 350 bar at ports A, B, and P, allowing it to control high-pressure actuators, while the return line at port T is limited to 160 bar to protect tank side seals. A peak flow capacity of 60 l/min keeps pressure losses moderate in medium-size circuits. The mounting face follows the ISO 4401-03-02-0-05 porting pattern so the unit fits standard size 03 subplates without adapter blocks. An FKM seal set resists common hydraulic oils and elevated temperatures, safeguarding internal leakage paths. Functional safety calculations assign an MTTFd of 300 years, which supports integration into machinery requiring high reliability metrics. These features balance pressure capability, flow rate, and interface compatibility to make the valve a straightforward choice for directional control in automated hydraulic machinery.
