The 4WE6D6X/EG24N9DK24L/62SO43A-1170 CSA directional spool valve is produced by Bosch Rexroth in the WE Directional Spool Valves series. It routes pressurized fluid to the required actuator ports in hydraulic automation systems. The body uses the ISO 4401-03-02-0-05 mounting interface to fit standard subplates. Channels a, b, and p tolerate operating pressure up to 350 bar, while the t port is rated for 210 bar DC. During direct current operation it can pass 80 l/min and shift up to 4.2 cycles per second. A 24 V DC coil rated at 30 W drives the spool and can remain energized continuously thanks to a 100 % duty cycle. Electrical hookup is through an M12x1 four-pin DK24L connector that simplifies plug-in wiring.
The coil surface may reach 120 °C, so installers must provide adequate heat dissipation. An IP65 enclosure keeps dust and low-pressure jets of water away from internal components. The design holds protection class III according to VDE 0580, allowing operation from a safely isolated low-voltage supply. Internal suppression limits switch-off transients, yet overvoltage up to 500 V can still appear across the coil when the field collapses. Hydraulic oil cleanliness should stay within ISO 4406 code 20/18/15 to prevent spool abrasion. Statistical analysis gives a mean time to dangerous failure of 300 years, supporting long service in critical circuits. With both solenoids fitted the assembly weighs 1.95 kg, which aids manual installation.
