The 4WRZ25W6-220-7X/6EG24N9TK4/D3M belongs to the WRZ Proportional Directional Valves series produced by Bosch Rexroth for hydraulic automation where variable flow and accurate spool positioning are required. A nominal flow of 220 l/min at a 10 bar differential allows the valve to handle high-volume circuits, while a maximum operating pressure of 350 bar permits use in demanding pressure lines. The ISO 4401-08-07-0-94 mounting pattern aligns the body with common subplates so manifold assembly is straightforward. Mineral oil of the HL or HLP type is specified as the working medium, and a viscosity range of 20 to 380 mm²/s ensures stable behavior across typical service conditions. Hydraulic fluid can enter the valve at temperatures from –20 to 80 °C, enabling cold starts and elevated-temperature duty cycles. Pilot control is supported by a 7 l/min pilot oil flow and a 10 cm³ pilot oil volume, delivering responsive proportional movement of the main stage.
The electromagnet that shifts the spool is powered by a 24 V DC coil whose resistance is 4.8 Ω at 20 °C, setting a predictable electrical load for drive electronics. A maximum coil current of 1.5 A defines the peak output the amplifier must supply during full command signals. The DIN EN 175301-803 connector forms the electrical interface, allowing quick replacement without rewiring. An IP65 protection rating guards internal components from dust ingress and water jets, so enclosure in a separate cabinet is not mandatory. NBR seals are fitted to keep mineral oil contained and prevent external contamination. The assembled valve weighs 18.2 kg, a consideration for mounting hardware and manual handling during service.
