4WE6E73-6X/EG24N9DK35L/A12 CSA AN

The 4WE6E73-6X/EG24N9DK35L/A12 CSA AN valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth. Intended to shift hydraulic flow between actuator ports, it uses a 24 V DC solenoid rated at 1.25 A so that control cabinets can drive it from standard machine power supplies. The coil draws 30 W at nominal conditions, and the 100 % duty cycle allows the valve to remain energized without enforced cooling pauses. A maximum coil surface temperature of 120 °C defines the thermal limit before insulation aging accelerates. Electrical connection is made through an M12 × 1 four-pole plug coded DK35L, simplifying quick replacement in modular manifolds. The enclosure reaches IP65, preventing dust ingress and water jets from impairing operation, while Protection Class III architecture keeps all live parts on a safe extra-low-voltage level. Mounting follows the ANSI B93.9 porting pattern, so it matches common subplates without adapters. With both solenoids installed, the assembly weighs 1.95 kg, keeping manifold loads low.

In service, the spool tolerates fluid that meets ISO 4406 cleanliness class 20/18/15, which reduces silt abrasion and assures consistent metering edges. A concealed manual override designated N9 lets technicians shift the spool mechanically during commissioning or power loss without disturbing the coil housing. Hydraulic capacity reaches 80 l/min on direct current actuation, and the pressure envelope tops out at 350 bar on ports P, A, and B, permitting use on high-pressure circuits for cylinders and motors. Back-pressure in the tank line may reach 210 bar, so return plumbing can be routed through counterbalance valves without risk of seal extrusion. The valve can change state once per second, a switching frequency that limits heat buildup during continuous cycling. These limits position the unit for precise directional control in automated presses, injection molding machines, and mobile hydraulic platforms.
