The 4WE6E6X/EW24N9K4/ZV directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is intended to switch hydraulic flow paths in automated machinery. Its size 6 body follows the ISO 4401-03-02-0-05 porting pattern, so it mates with standard subplates in compact power units. A clamping length of 22 mm sets the spacing for mounting screws and helps keep the valve centered on the manifold. The solenoid is designed for a nominal supply of 24 V, and the ±10 % voltage tolerance maintains reliable actuation when the control circuit experiences minor fluctuations. Continuous energization is permitted because the coil is rated for a 100 % S1 duty cycle, while a maximum coil surface temperature of 120 °C prevents thermal damage during prolonged operation. Electrical transient stress is limited by a maximum switch-off overvoltage of 500 V, and the hydraulic section withstands operating pressures up to 350 bar to suit high-pressure circuits.
Wiring is completed through a K4 connector conforming to DIN EN 175301-803, which provides a quick plug-in interface for field replacement. When mated, the enclosure reaches an IP65 protection class so dust and low-pressure water jets do not penetrate the coil housing. A concealed N9 manual override lets maintenance staff shift the spool without power, and the feature can be used as long as tank pressure stays below 50 bar. The valve can be installed in any orientation, giving designers freedom to place it in tight manifolds. FKM seals resist common hydraulic fluids and keep external leakage low. Reliable function depends on fluid cleanliness held to ISO 4406 20/18/15, which minimizes wear on the precision spool surfaces.
