The 4WRKE32W6-600L-3X/6EG24K31/A1D3M directional valve is part of the 4WRKE Directional Valves series from Bosch Rexroth and is built to meter flow in automated hydraulic systems. It is produced with a nominal size of 32 and employs a W6 spool whose L linear characteristic provides proportional flow change relative to signal input. At a differential pressure of 10 bar the valve reaches a nominal flow of 600 L/min, making it appropriate for circuits that need steady medium-high capacity. Port diameters of 38 mm match the ISO 4401-10-08-0-94 mounting pattern, so the unit bolts directly to standardized subplates. Drive electronics operate from a 24 V DC supply, and command values are received as analogue ±10 V through the A1 interface, allowing direct connection to common motion controllers.
Electrical termination is accomplished with a DIN EN 175201-804 connector; once the plug is fastened the assembly attains IP65 protection against dust and water jets. The solenoid system draws a maximum of 72 W, a factor to consider when sizing the control power supply. Hydraulic passages accommodate up to 1600 L/min of main flow, and the ports tolerate operating pressures as high as 350 bar. Pilot control needs only 13.0 L/min, which keeps auxiliary pump demand low while still enabling quick spool shifts. The complete valve weighs 31.5 kg, so mounting surfaces must support this mass without distortion. These electrical and hydraulic limits define the practical envelope in which the valve can reliably direct large actuator movements in industrial automation.
