The 4WRZE16E100-7X/6EG24N9TK31/A1D3V proportional directional valve is manufactured by Bosch Rexroth for the WRZ Proportional Directional Valves series. It directs and meters hydraulic flow in automated machinery, using an ISO 4401-07-06-0-94 mounting interface that matches subplate ports in size 16. A nominal flow of 100 l/min at a differential pressure of 10 bar defines the valve’s rated throughput, while a maximum operating pressure of 350 bar permits use in high-pressure circuits. The integrated solenoid is energized at 24 V DC; its 2 Ω resistance at 20 °C sets a steady-state current that can be held continuously because the duty cycle is 100 percent. Spool position is commanded with an analog ±10 V signal, allowing proportional adjustment of flow direction. Thermal endurance is secured by a coil temperature limit of 150 °C, ensuring reliable magnetic force during prolonged operation.
The housing carries an IP65 ingress rating so internal components remain protected against dust and water jets, and wiring is completed through a DIN EN 175201-804 connector that simplifies field replacement. Control precision is aided by hysteresis not exceeding 6 percent, allowing repeatable response to successive command voltages. The main stage requires fluid cleanliness of ISO 4406 20/18/15 and is intended for mineral oil of the HL or HLP classes to maintain seal integrity. Internal drainage tolerates return-line pressures up to 30 bar without affecting spool movement. The assembled unit weighs 13.6 kg, which must be considered when mounting on manifolds or frames. These characteristics complete the operating profile needed for proportional flow and directional control in hydraulic automation.
