The 4WE6Y73-6X/EG24N9K4/A12V directional spool valve is manufactured by Bosch Rexroth as part of the WE Directional Spool Valves series and serves to route pressurized fluid in hydraulic automation circuits. The valve is built to nominal size 6 and is energized by a 24 V DC solenoid that draws a rated current of 1.25 A. Its coil absorbs 30 W under direct-current operation, while insulation class F materials protect the windings. The design permits a coil surface temperature up to 120 °C during continuous duty, and the housing meets IP65 ingress protection to resist dust and water spray. A concealed N9 manual override lets technicians shift the spool without electrical power.


The clamping length is 42 mm, providing secure attachment to mounting plates. Connection to the hydraulic manifold uses the ISO 4401-03-02-0-05 interface, and ports follow the NFPA T3.5.1 D03 pattern. FKM seals withstand common hydraulic fluids and elevated temperatures. The valve accommodates flows to 80 l/min, sustains 350 bar on pressure and service ports, and tolerates 210 bar on the tank return. Dynamic duty is supported by a switching frequency of 4.2 cycles per second, giving responsive performance in automated systems.
