The 4WE6E6X/EW110N9DK25L/62SO43A-1750 is a directional spool valve produced by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow between ports inside automation manifolds. The solenoid is designed for a nominal voltage of 110 V AC and draws 0.39 A at 60 Hz to shift the spool. During energizing, it requires 220 VA switch-on power, while steady holding power falls to 50 VA to limit heating. Continuous operation is supported by a 100% ED duty cycle and an H insulation class that withstands elevated coil temperatures. Electrical connection is provided through a DK25L five-pole plug, giving quick coupling to cabinet wiring, and the housing carries an IP65 protection class to block dust and low-pressure water jets.
The hydraulic section passes up to 60 l/min and tolerates 350 bar at ports P, A, and B, enabling high-pressure circuits. Port T is restricted to 160 bar to protect tank lines. Maximum switching frequency is 2 cycles per second, allowing rapid directional changes without overheating. The coil surface may reach 120 °C during rated service, so users must account for nearby components. Mechanical alignment is aided by a locating hole fitted with a locking pin conforming to ISO 8752-3×8, and the mounting face follows the ISO 4401-03-02-0-05 porting pattern for interchangeability with standard subplates. The assembly weighs 1.95 kg when equipped with two solenoids, keeping manifold loads moderate.
