4WE6J6X/EW110N9DAL/B10 CSA

The 4WE6J6X/EW110N9DAL/B10 CSA directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow to actuators in automated machinery. With a size 6 envelope, the valve fits compact manifolds while still providing the passage area needed for medium flow tasks. Its four ports support typical A, B, P, and T connections so circuits can reverse actuator motion. The porting follows the ISO 4401-03-02-0-05 pattern to ensure interchangeability with standard subplates, and the NFPA D03 mounting face further simplifies installation in North American assemblies. Electrical wiring is completed through a 1/2-14 NPT cable gland designated DAL, giving strain relief for armored cable. The coil is wound for 110 VAC supplies so it can be powered from common control transformers, and compatibility with 50 Hz or 60 Hz mains avoids the need for frequency-specific parts. At energization the coil draws 220 VA, providing rapid spool shifting for decisive flow changeover.

Once the valve is pulled in, holding demand falls to 50 VA, which limits heat rise in continuous duty service. The coil is designed for a 100 percent duty cycle, allowing it to remain energized without time limits during closed-loop positioning routines. A concealed manual override identified as N9 lets maintenance staff shift the spool mechanically when power is unavailable. The pressure containing body withstands 350 bar on the service ports so the component can operate in high-pressure power units, while the tank port is limited to 160 bar to protect return lines. Flow capacity reaches 60 L/min, matching mid-sized cylinders and motors. An IP65 enclosure rating keeps dust and water jets from compromising the electrical connection in wash-down zones. The factory-installed throttle insert with a 1.0 mm orifice in port P, marked B10, dampens pressure surges during coil switching to improve circuit stability.
