4WE6G73-6X/EG12N9K4

The 4WE6G73-6X/EG12N9K4 valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation systems that require reliable flow direction control. It uses a 12 V DC coil voltage so that the solenoid can be powered directly from mobile equipment or battery-backed control panels, while the rated current of 2.5 A defines the electrical load the driver circuit must supply during actuation. An F-class insulation system permits the winding to endure higher internal temperatures without degradation, and the permissible coil surface temperature of 120 °C marks the upper thermal limit for sustained duty cycles. A 3-pole connector with two power pins and one protective earth is provided to simplify wiring and maintain ground continuity, and the IP65 protection class prevents dust ingress and water jets from affecting the electrical parts in outdoor or wash-down environments.

The valve body mounts on subplates that follow NFPA T3.5.1 D03, and the ISO 4401-03-02-0-05 porting pattern aligns its pressure and work ports with common size 03 manifolds, allowing fast interchange without re-machining. A concealed manual override lets maintenance staff shift the spool locally while guarding against unintended activation during normal service. Hydraulic capability reaches a maximum operating pressure of 350 bar, giving the unit the strength to handle high-pressure supply lines, and a rated flow of 80 l/min determines the volume it can route without excessive pressure loss. The T port can tolerate up to 210 bar back pressure, so return lines may run at elevated levels in counterbalance circuits. A mass of 1.95 kg keeps the component lightweight, minimizing stress on compact valve stacks and easing manual installation.
