4WE6E73-6X/EG24N9K4

The 4WE6E73-6X/EG24N9K4 directional spool valve is built by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow for automation circuits and fits nominal size 6, so it mounts on compact subplates with minimal pressure drop. The ISO 4401-03-02-0-05 porting pattern aligns its P, A, B, and T galleries with standard CETOP 03 base plates to simplify installation. Channels P, A, and B withstand operating pressures up to 350 bar, which lets the valve manage high-pressure actuator lines without external relief valves. A maximum flow of 80 l/min is permitted in direct current service, providing sufficient volume for medium-speed cylinders. The solenoid coil is rated for a 24 V DC supply, and it draws 1.25 A, enabling direct connection to common machine control outputs. Voltage may vary by ±10 % while still holding the spool in position, and the 100 % ED duty cycle allows continuous energization in demanding cycles without overheating.

In the return path, port T is limited to 210 bar during direct current operation, protecting tank lines from excess load. The coil’s nominal power consumption of 30 W defines the heat that must be removed by the surrounding fluid or ambient air. An IP65 protection class keeps dust and low-pressure water jets away from the electrics when the mating connector is secured. The electrical interface follows DIN EN 175301-803 form K4, so the valve plugs into industry-standard rectangular connectors. A concealed manual override identified by code N9 lets technicians shift the spool locally without disturbing enclosure seals. The internal cleanliness requirement of ISO 4406 20/18/15 limits particulate levels and helps maintain predictable switching forces. With a mass of 1.95 kg, the component can be handled easily during manifold assembly.
