The 4WRZE10EB85-7X/6EG24N9EK31/A1D3V belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and modulates hydraulic flow and direction in automated machinery. It is energized by a 24 V DC supply voltage that feeds the on-board electronics, while a ±10 V command signal accepts setpoints from motion controllers. A coil resistance of 2 Ω at 20 °C keeps winding impedance low so current rises quickly during actuation. The coil can draw up to 2.5 A, and normal operation is supported with a 100 % duty cycle for continuous service. Maximum current consumption of the integrated amplifier is limited to 1.8 A so power supplies can be sized accordingly. Thermal limits are defined by a 150 °C maximum coil temperature, and an IP65 degree of protection seals the housing against dust ingress and low-pressure water jets during wash-down cycles.
The valve handles a nominal flow of 85 l/min at a 10 bar differential, making it suitable for medium-capacity circuits. System pressure capability reaches 315 bar, and the same 315 bar rating on port T allows external draining without additional relief components. Port Y is limited to 30 bar, protecting the pilot stage from excess back-pressure. Dynamic control is aided by a pilot oil flow of 3.5 l/min for a full 0–100 % stroke change and a pilot oil volume of 1.7 cm³ that governs the spool’s displacement. Mounting follows the ISO 4401-05-05-0-94 porting pattern, enabling interchange with other size 05 subplates. An integrated ZDR 6 DP0-4X/40YM-W80 pressure-reducing valve holds the pilot supply at a constant level so the main stage responds predictably under varying load conditions.
