The 4WE6D6X/EG24N9DK72LSO407 CSA AN unit is produced by Bosch Rexroth for the WE Directional Spool Valves series and directs hydraulic flow to actuators in automated machinery. It is energized by a 24 V DC coil, so it can be driven directly from common machine control supplies; the permissible ±10 % voltage window protects performance during power variations. When the coil is held on, it draws 8 W, limiting panel heat load. The coil insulation is rated so that the outer surface may reach 85 °C without damage, supporting use in warm manifolds. A concealed manual override lets maintenance staff shift the spool without electrical power while preventing accidental activation. The unit can be mounted in any orientation, which simplifies manifold layout. Connection to subplates follows the ANSI B93.9 porting pattern, allowing quick replacement with other valves on the same standard footprint.
For mechanical integration, the clamping length of 42 mm matches standard retaining bolts on size 6 cavities. Oil entering the valve should meet cleanliness class 20/18/15 according to ISO 4406 to avoid spool wear and sticking. The electromagnetic assembly is specified for a 100 % duty cycle (S1), so it can remain energized indefinitely during long holding periods. Hydraulic capacity is defined by a maximum flow of 60 l/min, enabling medium circuit throughput. Pressure limits are 315 bar on the supply and work ports and 210 bar on the tank port, ensuring safe operation within typical industrial systems. Despite these ratings, the assembled valve weighs 1.95 kg, allowing easy handling during installation.
