The 4WRZ10W8-85-7X/6EG24N9EK4/D3M is produced by Bosch Rexroth for the WRZ Proportional Directional Valves series and directs hydraulic flow in automated machinery. It is energized by a 24 V DC supply, drawing up to 1.5 A through a coil that measures 4.8 Ω at 20 °C. A 100 % duty cycle allows uninterrupted operation, while the coil withstands temperatures to 150 °C without thermal damage. The housing carries an IP65 rating to block dust and low-pressure water jets, and electrical hookup is completed through a DIN EN 175301-803 connector. Overall mass is 7.8 kg, so manifold mounting must support that load.
This model passes 85 l/min at a 10 bar pressure drop and tolerates 315 bar on the main ports as well as on the external drain at port T. Pilot oil is taken internally, but the control chamber vents externally through port Y to keep pilot pressure low. A D3 pressure-reducing valve is integrated to stabilize the pilot circuit, and an N9 concealed manual override lets technicians shift the spool during setup without powering the solenoid. Installation aligns with the ISO 4401-05-05-0-94 porting pattern, providing compatibility with standard subplates.
