The 4WRZE25W6-220-7X/6EG24N9ETK31/F1D3M proportional directional valve is built by Bosch Rexroth for the WRZ Proportional Directional Valves series and regulates actuator speed and direction in hydraulic automation circuits. With a valve size of 25, it fits systems that call for medium-frame components while still managing a maximum main flow of 870 l/min for rapid cylinder motion. A nominal flow of 220 l/min at a 10 bar pressure drop offers predictable metering during steady operations, and the unit withstands main line pressures up to 350 bar to suit high-pressure power units. The ISO 4401-08-07-0-94 mounting pattern lets it bolt to standard subplates, and a weight of 18.4 kg must be considered when planning manifold support. Internal pilot oil supply and drainage simplify plumbing because no external pilot lines are required, while a concealed manual override (N9) lets technicians shift the spool locally without exposing protruding levers. The return port tolerates up to 30 bar when draining internally, and NBR seals contain mineral oil without swelling.
Electronic control is handled through a 4 to 20 mA command value input, allowing the valve to receive standard current loops from programmable controllers. The integrated amplifier draws a nominal 24 V DC supply, and its peak current consumption reaches 1.8 A during continuous modulation. Short switching pulses can rise to 3 A, giving the solenoids added force for fast spool acceleration without overstressing the power supply. Electrical connection is made through a plug that follows the DIN EN 175201-804 standard, enabling quick replacement with commonly stocked cable sets. The housing carries an IP65 protection rating, so the assembly resists dust ingress and low-pressure water jets when a matching connector seal is used. These electrical characteristics let the valve interface reliably with modern control cabinets while maintaining the hydraulic performance detailed earlier.
