The 4WEH16L7X/6EG24N9S2K4 valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth and is used to route hydraulic flow in automated machinery. Actuation is electro-hydraulic, so an internal pilot stage shifts the main spool once energized. The unit is built in nominal size NG16, and with symbol L it carries up to 300 l/min to cylinders or motors. Ports A and B withstand 280 bar, permitting high-load motion control, while pilot pressure may reach 250 bar and must be at least 14 bar for a spring-centered spool to move. The pilot return line tolerates 210 bar, letting designers connect it to circuits with moderate back-pressure. Electrical power is 24 V DC supplied through a DIN EN 175301-803 connector, and a concealed manual override (N9) lets technicians shift the spool when power is unavailable.
The body follows the ISO 4401-07-07-0-05 porting pattern so it mates with standard subplates without adaptation. During installation, M10 screws are tightened to 58 Nm to resist hydraulic forces that try to separate the valve from its manifold. A protective coating up to 100 µm thick shields the housing against corrosion in damp or chemically aggressive environments. Hydraulic fluid must meet ISO 4406 cleanliness level 20/18/15 to prevent abrasive wear on the precisely fitted spool lands. Switching time is tuned with S2 discharge control, allowing maintenance personnel to match response speed to system dynamics without external throttling devices. These features define the valve’s suitability for precise, high-duty directional control tasks in industrial power units and motion assemblies.
