The 4WE6D6X/EG24N9DK35LSO43A-1807 CSA valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation that requires electrically driven flow reversal. It occupies nominal size 6 (NG6), matching compact manifolds where space is limited. The porting pattern follows ISO 4401-03-02-0-05 so it bolts directly to standardized subplates. A, B, and P ports tolerate 350 bar, allowing the spool to manage high supply pressure, while the T port is limited to 210 bar to protect return circuits. A maximum DC flow of 80 l/min supports moderate actuator speeds. The coil is energized with a nominal 24 V DC input, and a voltage tolerance of ±10 % keeps actuation reliable under line variations. At that voltage the valve draws 1.25 A, simplifying fuse selection for machine builders.
The electromagnetic section consumes 30 W during steady duty to develop the force needed for spool movement. An M12×1 four-pin DK35L connector provides a quick and sealed electrical interface for field wiring. Coil surface temperature may reach 120 °C, so adjacent components must withstand elevated heat. The housing carries an IP65 rating, preventing dust ingress and low-pressure water spray. A concealed manual override lets maintenance staff shift the spool without energizing the coil, while reducing the chance of inadvertent operation. Maximum switching frequency is 4.2 cycles per second in DC service, enabling rapid directional changes in servo loops. Cleanliness class ISO 4406 20/18/15 defines the fluid filtration level required to maintain clearances and extend valve life. These electrical and environmental provisions allow the valve to operate reliably in decentralized, machine-mounted locations.
