The 4WE6J73-6X/EG12N9K4/A12/62 valve is part of the WE Directional Spool Valves series from Bosch Rexroth and is used to shift hydraulic flow paths in mobile and industrial systems. Its solenoid is rated for a 100 percent duty cycle so it can remain energized continuously without overheating. The coil consumes 30 W, which limits heat rise and allows dense manifold layouts. The device is energized at 12 V DC and draws a steady 2.5 A, enabling direct connection to low-voltage control supplies. A voltage tolerance of ±10 percent protects operation when battery or supply levels fluctuate. Electrical connection is through a DIN EN 175301-803 plug coded K4 that provides sealed engagement for field wiring, and an IP65 housing rating further shields the valve against dust and water spray. A concealed manual override identified as N9 lets maintenance staff shift the spool locally during commissioning or in case of power loss.
The hydraulic section accommodates a maximum flow of 80 l/min, letting the valve serve medium-size actuators. Ports a, b, and p withstand operating pressures up to 350 bar, while the tank port is limited to 210 bar to match reservoir return lines. NFPA D03 mounting simplifies installation on standard subplates, and the ISO 4401-03-02-0-05 porting pattern aligns the internal passages with international manifold layouts. A locating pin conforming to ISO 8752-3x8-St (/62) centers the body during assembly to prevent leakage paths. Smooth switching behavior coded A12 reduces pressure surges when the spool shifts, protecting downstream components. These mechanical parameters combine to support reliable directional control in closed-loop or on/off hydraulic circuits.
