4WE6E6X/EW110N9DK25L/ZV/62 AN

The 4WE6E6X/EW110N9DK25L/ZV/62 AN directional spool valve is manufactured by Bosch Rexroth as part of the WE Directional Spool Valves series and is used to route pressurized oil between actuator ports in automated hydraulic circuits. The integrated solenoid operates on a nominal voltage of 110 V at 50 or 60 Hz, so the unit can be wired to common plant power without a transformer. A switch-on power demand of 220 VA produces the magnetic force required to overcome spring preload and shift the spool, after which the holding power drops to 50 VA to reduce heat and energy use. Continuous service is supported because the coil is rated for a 100 % duty cycle, and a voltage tolerance of ±10 % allows dependable switching despite line fluctuations. At 50 Hz the coil draws 0.52 A, while at 60 Hz it needs 0.39 A, giving designers clear data for fuse sizing and control relay selection. The ANSI B93.9 (NFPA D03) porting pattern matches industry standard sub-plates, simplifying manifold layout and replacement.

The valve body clamps to the sub-plate with a 22 mm mounting length, ensuring the O-ring lands seat correctly against the manifold surface. FKM seals are fitted to provide chemical resistance to a broad range of hydraulic fluids and maintain leakage control at elevated temperatures. The hydraulic section handles flows up to 60 l/min, and the pressure limits reach 350 bar on ports a, b, and p, allowing the device to control medium-sized actuators in high-pressure systems. Return flow through port t is limited to 160 bar when the coil is powered by an AC supply, protecting the tank line from over-loading. A cleanliness class requirement of 20/18/15 per ISO 4406 reduces the risk of spool sticking by keeping particulate contamination at acceptable levels. The coil surface temperature may rise to 120 °C during continuous operation, so surrounding components must be selected for that heat exposure. An IP65 protection class prevents dust ingress and water jets from affecting the solenoid, supporting reliable service in factory wash-down zones.
