The 4WE6U12-6X/EW110N9DAL/V directional spool valve is produced by Bosch Rexroth in the WE Directional Spool Valves series. It directs hydraulic flow in automated systems by shifting an internal spool to connect or block pressure lines. Valve size 6 defines the port dimensions and matches subplates in compact power units. The ISO 4401-03-02-0-05 porting pattern aligns the body with standard CETOP 03 mounting faces. A maximum operating pressure of 350 bar on ports P, A, and B enables use in high-pressure circuits, while the T port withstands up to 160 bar so return flow can be routed to pressurized tanks. The valve passes up to 60 l/min to satisfy moderate actuator speeds. Its solenoid coil is designed for a 110 V 50/60 Hz supply, and a ±10 % voltage tolerance keeps performance stable under fluctuating mains. Switch-on power peaks at 220 VA to build magnetic force quickly and shift the spool without delay.
The holding power drops to 50 VA once the spool is in position, reducing heat and energy draw during continuous energization. A maximum switching frequency of two cycles per second sets the limit for rapid directional changes in servo-controlled loops. Coil surface temperature may reach 120 °C without degrading insulation, provided ventilation is sufficient. An IP65 rating guards the enclosure against dust and low-pressure water jets, allowing installation near hydraulic machinery. A concealed N9 manual override lets technicians reposition the spool during commissioning without exposing moving parts. Electrical termination is via a 1/2-14 NPT threaded conduit entry that matches common industrial fittings. Fluorocarbon FKM seals resist high temperatures and aggressive fluids so service intervals remain predictable.
