The 4WRZE25W6-325-7X/6EG24N9EK31/F1M proportional directional valve is produced by Bosch Rexroth for the WRZ Proportional Directional Valves series. It regulates flow and direction in hydraulic automation circuits where precise electro-hydraulic control is required. The valve size 25 provides a passage area suited for large machine actuators, while the W6 spool geometry establishes symmetrical metering edges for consistent flow in both directions. At a pressure drop of 10 bar the metering section passes 325 l/min, supporting high-speed cylinder movement, and the main stage tolerates operating pressures up to 350 bar so it can be installed in high-pressure lines. Mounting is completed on an ISO 4401-08-07-0-94 interface, which aligns the pressure and tank ports with standard sub-plates. A 24 V DC supply powers the integrated electronics; the current input F1 command interface converts control current into proportional spool position, and the circuit draws a maximum of 1.8 A during full stroke operation.
The pilot section employs size 6 components to shift the main spool quickly without imposing significant pilot flow demand. Pilot oil is taken internally from the pressure port, while excess pilot fluid returns externally, preventing back-pressure from affecting spool stability. Electrical connection is made through a DIN EN 175201-804 plug, allowing straightforward wiring in control cabinets. Continuous modulation is possible because the unit is rated for a 100 % duty cycle, and its IP65 housing resists dust and low-pressure water jets in typical industrial environments. A concealed manual override enables maintenance personnel to reposition the spool when power is unavailable without exposing moving parts. The assembled valve weighs 18.4 kg, so mounting hardware must support that load while keeping vibration within acceptable limits.
