The 4WE6W73-6X/EG24N9DK35L/A12 directional spool valve is built by Bosch Rexroth within the WE Directional Spool Valves series for hydraulic automation circuits. The NG6 nominal size matches compact manifolds, and the ISO 4401-03-02-0-05 mounting interface aligns the ports with standard subplates. A 24 V DC coil powers the valve, and the coil accepts a ±10 % voltage swing to tolerate supply variation on mobile or plant wiring. The solenoid draws 30 W at rated voltage, and a 100 % duty cycle permits continuous energization without thermal derating. Control wiring terminates on an M12×1 four-pin connector that includes an LED and surge protection for quick status checks. The winding is built to insulation class F so the coil resists elevated temperatures, while a concealed manual override lets technicians shift the spool mechanically when power is unavailable. The housing carries an IP65 ingress rating, sealing the internal components against dust and low-pressure water jets.
Hydraulic performance is set for systems that demand consistent flow control up to 80 L/min at ports p, a, and b. The valve withstands working pressures to 350 bar on those service ports, and the tank port tolerates 210 bar, allowing back-pressure in return lines without damage. Spool actuation can repeat up to 4.2 times per second, supporting rapid-cycle machines while maintaining the smooth switching function identified by code A12 to reduce hydraulic shock. During extended operation the coil surface may reach 120 °C, which stays within the limits of its insulation class and avoids premature insulation aging. These limits, together with the sealed enclosure and continuous duty rating mentioned earlier, position the 4WE6W73-6X/EG24N9DK35L/A12 as a dependable control element in pressure-intensive automation loops.
