The 4WE6D73-6X/EG24N9DK24L/A12V/62 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and is used to switch flow paths in hydraulic automation. Size 6 defines its mounting envelope for compact installations. The valve provides four ports, enabling bidirectional control of an actuator while maintaining a dedicated tank return. A porting pattern of ISO 4401-03-02-0-05 aligns the body with standard subplates and manifolds. The solenoid coil draws 30 W, defining the heat load that must be dissipated by the electrical enclosure. It is designed for a nominal supply of 24 V DC so standard machine power buses can operate the coil. Under that voltage it takes 1.25 A, which guides fuse selection and wiring gauge. A continuous duty rating of 100% ED allows the solenoid to remain energized without thermal cycling. A maximum switching frequency of 4.2 cycles per second limits command signal rate to avoid coil overheating and hydraulic shock.
The valve tolerates operating pressures up to 350 bar at ports A, B, and P, enabling use in high-pressure circuits. Tank port T is limited to 210 bar, so downstream plumbing must keep backpressure below that value. A rated flow of 80 l/min defines the maximum volume it can route without excessive pressure drop. Ingress protection to IP65 prevents dust and low-pressure water jets from affecting the solenoid housing. A central M12x1 four-pin connector provides a quick disconnect interface for control wiring. A concealed manual override lets maintenance technicians shift the spool when electrical power is unavailable. FKM seals resist common hydraulic oils and many synthetic fluids, extending service life. The body includes an ISO 8752-3x8 locating hole with a pin to keep the valve aligned on the mounting surface.
