The 4WE6J6X/EG12NK40/62SO43A-1799A directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It controls hydraulic flow by shifting a solenoid-actuated spool, allowing automated start, stop, and reverse of actuator circuits. The solenoid is designed for a 12 V DC supply, and the ±10 % voltage tolerance keeps switching performance stable on vehicle or mobile power nets. Under nominal conditions the coil draws 2.5 A and converts 30 W into the magnetic force required to move the spool, while a 100 % ED duty cycle permits continuous energization without thermal interruption. Electrical connection is made through a Deutsch DT04-2PA plug; when combined with the K40 variant housing the interface attains an IP69K rating that prevents water or dust ingress during high-pressure wash-down. A manual override is present so the operator can shift the spool during commissioning or power loss. Positioning in the manifold is secured by a locating hole sized to ISO 8752-3×8-St.
With a nominal size of 6, the valve matches standard cavity dimensions and keeps pressure drops low in compact manifolds. The porting pattern follows ISO 4401-03-02-0-05, which allows direct mounting on sub-plates that share the same international standard. Hydraulic capacity reaches 80 l/min, enabling medium-flow circuits to operate actuators at required speeds. Pressure limits are set at 350 bar for the P, A, and B work ports, while the T port tolerates 210 bar; these ratings permit use in high-pressure mobile and industrial systems. A maximum switching frequency of 4.2 actuation cycles per second lets control systems issue rapid directional commands without excessive wear. The assembled valve weighs 1.95 kg, light enough for stacked manifold arrangements yet sturdy enough to resist vibration.
