The 4WE6U12-6X/EW110N9DAL/B12V directional spool valve by Bosch Rexroth belongs to the WE Directional Spool Valves series and controls hydraulic flow paths in automated machinery. Its solenoid coil is rated for 110 V AC at 50 or 60 Hz, allowing connection to common control transformers, and it draws 0.39 A at 60 Hz to keep electrical load low. A duty cycle of 100% ED supports continuous energization without overheating, while a ±10% voltage tolerance maintains reliable actuation despite supply variation. The switch-on power requirement is 220 VA to shift the spool quickly, after which holding power drops to 50 VA to minimize energy consumption. A concealed manual override is included so maintenance personnel can shift the valve mechanically when power is absent.
Sized as a 6 valve, the unit handles system lines up to 350 bar on ports A, B, and P, and withstands 160 bar on the tank port to suit medium-pressure circuits. Maximum flow across the bore reaches 60 l/min, supporting moderate actuator speeds in compact installations. The mounting interface follows NFPA D03, and the porting pattern matches ISO 4401-03-02-0-05, enabling direct subplate mounting with standard gasket layouts. Electrical wiring enters through a 1/2-14 NPT cable gland for secure strain relief, and the enclosure meets IP65 to protect the coil from dust and water jets. These features combine to deliver dependable spool shifting in hydraulic automation where precise pressure limits, standardized mounting, and secure electrical coupling are required.
