The 4WRZE32E1-520-7X/6EG24ETK31/A1D3M proportional directional valve is part of the WRZ Proportional Directional Valves series produced by Bosch Rexroth for hydraulic automation tasks that need accurate flow and pressure control. It installs on the ISO 4401-10-08-0-94 mounting pattern, allowing quick replacement on standardized manifolds. A nominal flow capacity of 520 l/min at a 10 bar differential supports large-volume circuits, and the unit tolerates system pressures up to 350 bar for heavy-duty workholding or press functions. Control commands arrive as a ±10 V input signal that shifts the spool proportionally, while a 24 V DC supply powers the onboard amplifier. The plug conforms to DIN EN 175201-804 so field wiring can be completed with common industrial connectors. During energization a 3 A power pulse drives the armature rapidly to its target, after which the electronics draw 1.8 A to hold position and limit heat generation.
Total hysteresis remains at or below 6 % so the commanded spool position can be repeated with minimal deviation. Both pilot-oil supply and pilot-oil drain are internal, eliminating external lines and reducing installation space. The tank port may see up to 30 bar, a limit that protects the return circuit when back-pressure accumulates. Flow passages A, B, P, and T are machined to 38 mm in diameter to match the high flow rating without excessive velocity. NBR sealing elements contain the fluid and resist common mineral oils used in industrial hydraulic systems. A built-in ZDR 6 DP0-4X/40YM-W80 pressure-reducing valve keeps the control pressure constant so the main stage receives a stable pilot signal. The accompanying subplate weighs 42.2 kg, providing mass that damps vibration and anchors the valve securely on large manifolds.
