The 4WE6HB6X/EG24N9K73L valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow to actuators in automated machinery and supports compact layouts thanks to a nominal size of 6. The ISO 4401-03-02-0-05 porting pattern aligns with standard subplates, and an NFPA D03 interface permits direct mounting on widely used manifolds. The spool tolerates 350 bar at ports P, A, and B, while the tank port is limited to 210 bar to safeguard return lines. A maximum flow of 80 l/min sustains medium-power circuits without cavitation. A concealed manual override identified by code N9 lets technicians shift the spool during setup, yet keeps moving parts protected during regular service. An IP65 enclosure rating seals the solenoid housing against dust and water jets, making the valve suitable for open plant environments.
The integrated solenoid operates on 24 V DC within a ±10 % voltage window, drawing a rated current of 1.25 A. Its 30 W power rating defines steady heat output, and a 100 % ED (S1) duty cycle allows uninterrupted energization during long holding periods. The maximum coil surface temperature of 120 °C indicates the thermal ceiling that must not be exceeded beside temperature-sensitive hoses or wiring. Electrical hookup uses an M12×1 four-pin connector marked K73L for quick, sealed connection changes. These electrical limits combine with the hydraulic capabilities described above to give the valve balanced performance in presses, molding machines, and other automated stations.
