The 4WE6D6X/OFEW110N9DAL/B10 CSA valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It is installed in hydraulic automation to route fluid between actuator ports in response to an electrical command. The valve operates on a nominal supply of 110 V AC, and the coil accepts 50/60 Hz line frequency to match standard power systems. Switch-on power draws 220 VA to shift the spool rapidly, after which holding power falls to 50 VA to limit heat and energy use. Voltage tolerance of ±10 % lets the coil function when mains vary within common industrial limits. The duty cycle is rated at 100 % ED so the solenoid may remain energized continuously without thermal damage. A concealed manual override labeled N9 permits mechanical actuation during commissioning or power loss.
External features include a 1/2-14 NPT conduit entry marked DAL for straightforward wiring, while an IP65 enclosure rating shields internal parts against dust and water jets. The maximum coil surface temperature reaches 120 °C, emphasizing the need for correct thermal management. On the hydraulic side the ISO 4401-03-02-0-05 porting pattern aligns with standard subplates, and a 1.0 mm throttle insert in port B, coded B10, moderates flow for smoother cylinder deceleration. The valve handles up to 350 bar on ports A, B, and P, and withstands 160 bar on the tank port to protect return lines. It passes 60 l/min at rated conditions, supporting medium-flow circuits. These pressure and flow capabilities combine with the continuous duty design to deliver reliable directional control in industrial machinery.
