The 4WE6J6X/EW110NK4/B10V directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series and directs hydraulic flow in automated machinery. Its solenoid coil operates on 110 V AC at 50/60 Hz, and the winding tolerates voltage variations of ±10 percent to accommodate common power fluctuations. Continuous energization is allowed because the coil is rated for a 100 percent ED duty cycle. When first energized it draws 220 VA, then settles to a 50 VA holding demand to reduce thermal load. Electrical termination is handled by a DIN EN 175301-803 form K4 plug, facilitating quick field replacement. A manual override is provided for commissioning or emergency actuation, and this override may be used while the tank line remains below 50 bar. These electrical and control features let the valve switch circuits reliably without auxiliary pilot pressure.
The hydraulic section accepts a maximum pressure of 350 bar at ports A, B, and P, while the tank ports withstand up to 160 bar, enabling use in high-pressure return systems. It passes up to 60 l/min, making it suitable for medium-flow actuator groups. The mounting face follows ISO 4401-03-02-0-05, and a 1.0 mm throttle orifice in port P dampens pressure surges during spool shifts. To protect the precision lands, system oil must meet ISO 4406 cleanliness class 20/18/15. FKM seals resist aggressive hydraulic fluids and elevated temperatures, extending service life. An IP65 enclosure rating shields the coil and terminals from dust and water jets when the connector gasket is fitted, permitting installation on exposed machinery without separate housings.
