The 4WE6D6-6X/EG110N9K4/V CSA directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and shifts hydraulic flow paths in automated machinery. It bolts to subplates that follow the ISO 4401-03-02-0-05 porting pattern, so swap-out with other CETOP 3 units is direct. Working pressure can reach 350 bar at ports P, A, and B, which suits high-pressure circuits, while the D6 spool permits a maximum flow of 80 l/min for medium-capacity actuators. The solenoid operates on 110 V DC within a ±10 percent tolerance, draws 0.25 A, and dissipates 30 W, giving designers clear electrical loading figures. A 100 percent duty cycle classification allows the coil to remain energized continuously without scheduled cooling intervals.


Field wiring is carried out through a DIN EN 175301-803 K4 connector, and once mated the assembly attains an IP65 enclosure rating against dust and water jets. The winding meets insulation class F, so the coil surface may rise to 120 °C without degrading insulation life. A concealed N9 manual override lets service personnel shift the spool during commissioning or power loss, and it withstands up to 50 bar on the tank line when pressed. System backpressure of 210 bar can be present at the tank port without harming valve integrity, aided by FKM seals that resist mineral oil and many synthetic fluids. Together these features provide reliable solenoid actuation, manual fallback, and environmental protection within demanding hydraulic installations.
