The 4WRKE25W6-350L-3X/6EG24ETK31/A5D3M is produced by Bosch Rexroth as part of the 4WRKE Directional Valves series and is used to route hydraulic flow in automated machinery. It is built in nominal size 25 so it fits manifolds designed for that port spacing. A W6 linear spool provides proportional metering of the passage. The nominal flow reaches 350 L/min at a 10 bar pressure drop, offering steady delivery for medium-capacity actuators. For short bursts it can accept up to 870 L/min, allowing rapid cylinder movements when required. Ports p, a, and b tolerate operating pressures up to 350 bar, supporting high-pressure circuits. Pilot oil is internally supplied and drained, which removes the need for external pilot hoses. NBR seals contain the fluid and resist common mineral oils, and the housing is rated to IP65 to protect internal electrics from dust and water jets.
Analog control is achieved with a ±10 V command signal that modulates the spool position. The solenoid coil is energized from a 24 V DC supply, and the coil is removable so maintenance can be carried out without disturbing hydraulic lines. Electrical connection is provided through a DIN EN 175201-804 plug for standardized wiring. The valve mounts on an ISO 4401-08-07-0-94 subplate, facilitating direct installation on common manifolds. Spool movement repeatability is maintained with hysteresis not exceeding 1 percent, keeping position error low during small signal changes. During operation the electronics draw up to 72 W, a figure used when sizing power supplies and thermal paths. The assembly weighs 16.8 kg, so mounting brackets and machine frames must support that mass.
