The 4WRZE25W6-220-7X/6EG24N9TK31/A1V valve is built by Bosch Rexroth within the WRZ Proportional Directional Valves series for closed-loop hydraulic automation. It mounts on subplates that follow the ISO 4401-08-07-0-94 interface so maintenance crews can replace units without re-machining manifolds. A differential command of ±10 V controls the integrated electronics, causing the spool to shift proportionally and meter flow. Those electronics operate from a 24 V DC supply, draw a continuous current of 1.8 A, and accept a 3 A power pulse for rapid step responses. Wiring is completed through a DIN EN 175201-804 plug, giving standard pin assignments for feedback and power. When electrical power is absent, technicians can reposition the spool by using the concealed manual override labeled N9. Under a 10 bar pressure drop the valve passes 220 l/min, matching medium-flow cylinders and motors, and FKM seals maintain compatibility with mineral oils and higher temperatures.
Pilot oil enters the unit externally while drain oil leaves internally, reducing the number of return hoses in compact installations. The inlet port P measures 24 mm, and the A, B, and T ports each measure 25 mm to limit velocity-related losses across the body. The main stage withstands operating pressures up to 350 bar, allowing it to control actuators in high-pressure circuits; return pressure at the T port is limited to 30 bar to protect reservoir piping. A subplate weight of 18.4 kg stabilizes the assembly against vibration and helps damp pressure pulsations that develop during rapid spool shifts.
