The 4WE6Q23-6X/EW110N9K4 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is used to route pressure fluid in hydraulic automation circuits. Its ISO 4401-03-02-0-05 porting pattern allows direct mounting on standardized sub-plates, while a limit of 350 bar on ports A, B, and P ensures safe operation in high-pressure lines. The tank port can accept up to 160 bar so back-pressure does not damage the housing, and a maximum flow of 60 l/min supports medium-sized actuators without excessive pressure drop. A continuous 100 percent duty cycle lets the solenoids remain energized indefinitely in applications that require long holding times. The coil is supplied with 110 V AC, drawing a rated current of 0.52 A at 50 Hz, and it needs 220 VA during switch-on to overcome initial magnetic reluctance. With two solenoids installed the assembly weighs 1.95 kg, which assists in keeping manifold blocks compact.

The valve uses a DIN EN 175301-803 type K4 electrical connector so wiring can be completed with widely available industrial plugs. Its coil surface may reach 120 °C without loss of insulation integrity, and once the spool is shifted the holding requirement drops to 50 VA to conserve energy in continuous service. An IP65 enclosure rating protects the electrics from dust and water sprayed from any direction, making the unit suitable for machine frames that are cleaned down. A concealed N9 manual override is provided for commissioning or emergency shifting, and this feature can be operated safely as long as tank pressure stays below 50 bar. These characteristics complement the hydraulic limits noted earlier and confirm reliable service in automated systems.
