The 4WRZE32W8-520-7X/6EG24N9ETK31/F1D3V proportional directional valve is built by Bosch Rexroth as part of the WRZ Proportional Directional Valves series to regulate flow and direction in hydraulic automation circuits. It delivers a nominal flow of 520 l/min at a differential pressure of 10 bar and can pass up to 1600 l/min during peak demand, letting large actuators operate without cavitation. The valve withstands main pressures to 350 bar, so it suits high-pressure manifolds. An ISO 4401-10-08-0-94 porting pattern aligns the body with standard subplates for quick installation. Integrated electronics run from a 24 V DC supply, draw a continuous current of 1.8 A, and release a 3 A power pulse to shift the spool. A 100 % duty cycle supports uninterrupted service, while a maximum coil temperature rating of 150 °C prevents thermal damage in hot oil environments.
Control is provided through a 4–20 mA input signal, which allows closed-loop current controllers to set spool position precisely. Electrical connection is made with a DIN EN 175201-804 plug coded K31, and an IP65 housing keeps dust and water jets away from the coils and electronics. A concealed manual override identified as N9 permits local actuation without exposing moving parts. Pilot oil is taken internally and returned internally, and the pilot stage draws 15.9 l/min to position the main spool. The assembly weighs 42.2 kg, so mounting points must support that mass. These features combine to deliver reliable proportional control where analog commanding, sealed connections, and internal pilot circuitry are required.
