The 4WE6J6X/EG110N9K4/B10 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is used to route pressure and return lines in automated hydraulic circuits. The solenoid coil is sized for 30 W when operated on direct current, and at the nominal 110 V supply it draws 0.25 A, which keeps heat generation low in compact manifolds. The power stage accepts a ±10 percent voltage swing so performance remains stable with typical industrial line variations. Continuous energization is permitted because the duty cycle is 100 percent ED, supporting holding functions without extra cooling equipment. The body tolerates 350 bar on ports A, B, and P while the tank port withstands 210 bar, enabling the valve to handle high-pressure systems. A maximum direct-current flow rate of 80 l/min suits medium-size actuators, and the sub-plate interface follows ISO 4401-03-02-0-05 (D03) for easy replacement or modular stacking in existing blocks.
Electrical connection is made through a K4 plug conforming to DIN EN 175301-803, allowing quick field wiring and standardized cord sets. When the coil is supplied with alternating current, the solenoid requires 50 VA of holding power, which provides equivalent magnetic force without excessive consumption. For AC circuits the valve passes up to 60 l/min, and the armature can switch as fast as 4.2 cycles per second under direct-current excitation, supporting rapid directional changes in servo loops. A concealed N9 manual override is included so maintenance staff can shift the spool during commissioning or power loss without exposing the mechanism to contaminants. The housing carries an IP65 rating, protecting internal parts against dust and water jets in wash-down zones. A 1.0 mm throttle insert is fitted in port P to damp pressure peaks and improve metering accuracy when the valve opens or closes.
