The 4WE6D6X/OFEW110N9K4/B28 is a directional spool valve produced by Bosch Rexroth in the WE Directional Spool Valves series for hydraulic automation tasks that require precise flow control. It operates on a nominal supply of 110 V AC at 50 or 60 Hz, drawing 0.52 A at 50 Hz and 0.39 A at 60 Hz so conductors and fusing can be sized accurately. An initial switch-on power of 220 VA creates the magnetic force to shift the spool, after which the coil maintains position with a holding power of 50 VA to limit heat rise. Continuous energization is permitted by a 100 % duty cycle, and the coil surface may reach 120 °C, which defines clearance requirements for adjacent components. An IP65 enclosure stops dust and low-pressure water jets from entering, ensuring service in wash-down environments. The valve can be installed in any position, giving designers flexibility when routing pipework or stacking manifolds.
With a size 6 envelope, the valve follows the ISO 4401-03-02-0-05 mounting pattern so it fits D03 manifolds without adapters. The size designation keeps the spool diameter small and supports compact manifold layouts. Internal passages carry up to 60 l/min when powered by AC, delivering the flow needed for medium-capacity cylinders or motors. Ports A, B, and P withstand operating pressures to 350 bar, while the T port handles 160 bar back pressure, preserving seal integrity during return flow. Overall mass of 1.95 kg for the two-solenoid build simplifies manual installation, and the modest weight reduces stress on manifold hardware.
