The 4WE6J73-6X/EG24N9K4/A12R20 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series to switch hydraulic flow paths in automated machinery. Valve size 6 establishes the envelope and port centers, while the ISO 4401-03-02-0-05 (D03) porting pattern matches standard subplates for quick replacement. A maximum operating pressure of 350 bar at ports a, b, and p permits use in high-pressure circuits, and a 210 bar limit at the tank port safeguards the return line. The unit passes up to 80 l/min, and a 2.0 mm throttle insert in port B meters flow for controlled actuator speed. Electrical performance is defined by a 24 V DC coil that draws 30 W; a ±10 % voltage tolerance accepts common supply variation. Continuous energization is possible because the solenoid is rated for a 100 % duty cycle.
The DIN EN 175301-803 three-pole K4 connector provides a single pluggable interface for power and ground, streamlining field wiring. Insulation class F enables the coil to operate safely at elevated temperatures found in enclosed manifolds. A concealed manual override (N9) lets technicians shift the spool without energizing the coil, and the override remains functional up to 50 bar tank pressure. The 42 mm clamping length positions the body correctly in stacking assemblies, and the valve weighs 1.95 kg to allow installation by one person. Together these characteristics support dependable hydraulic actuation where precise, electrically controlled direction changes are required.
