The 4WRZ25E3-325-7X/6EG24N9K4/M valve belongs to the WRZ Proportional Directional Valves series and is produced by Bosch Rexroth for precise flow control in hydraulic automation. A 24 V DC supply energizes the solenoid, while a coil resistance of 4.8 Ω at 20 °C determines initial current draw. The circuit permits up to 1.5 A of coil current and supports a 100 percent duty cycle so the spool can be modulated continuously. Thermal endurance is defined by a 150 °C maximum coil temperature. Wiring is completed through a DIN EN 175301-803 plug, and once the matching cable socket is fitted the housing attains IP65 protection against dust and water.
Hydraulic capacity starts with a nominal flow of 325 l/min at a 10 bar differential and extends to 870 l/min for peak demand. The main ports tolerate operating pressures up to 350 bar, whereas return pressures must stay below 250 bar at port T and 30 bar at port Y. Installation occurs on a subplate that matches the ISO 4401-08-07-0-94 interface for manifold compatibility. Mineral oil of the HL or HLP grades is specified as the working medium. The assembled unit weighs 18.2 kg, an important consideration for handling and service access.
