The 4WE6D6X/OFEG24N9K4/62SO407 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow to actuators in automation circuits and is energized by a 24 V DC coil that draws 8 W under nominal conditions. The electrical system can accept supply variations of ±10 % and supports a 100 % duty cycle, so continuous operation is permissible without coil overheating. A maximum switching frequency of two cycles per second enables dependable response in moderately dynamic control loops. Thermal limits are defined by an allowed coil surface temperature of 85 °C, and ingress protection to IP65 guards the housing against dust and water jets. Connection is made through a DIN EN 175301-803 K4 plug, integrating the valve into standard machine wiring layouts.
The hydraulic design accommodates line pressures up to 315 bar on the P, A, and B ports, while the T port tolerates up to 210 bar; flow can reach 60 l/min when the direct-current solenoid is fully energized. A concealed N9 manual override lets service personnel shift the spool mechanically, and the override line is restricted to 50 bar to the tank to prevent component damage. Internal seals are NBR to ensure compatibility with common mineral oils, provided the fluid cleanliness meets ISO 4406 class 20/18/15. Two solenoids bring the assembled weight to 1.95 kg, allowing straightforward manifold mounting. Overall performance rests on the stated parameters, which make the valve suitable for compact hydraulic manifolds that demand reliable direction control under continuous electrical duty.
