The 4WRZE16W6-150-7X/6EG24K31/A1D3M proportional directional valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and regulates hydraulic flow and direction in automated machinery. It receives a command signal in a ±10 V range for proportional spool control, while the onboard electronics operate from a 24 V DC supply and restrict coil current to 2.5 A. Signal and power reach the unit through a DIN EN 175201-804 connector, and overall hysteresis is held to 6 % or less for repeatable positioning. When the matching cable socket is used, the enclosure meets IP65 to resist dust and water. Mechanical attachment relies on the ISO 4401-07-06-0-94 interface for size 16 subplates.
The main stage works at pressures up to 350 bar and delivers a nominal flow of 150 l/min with a 10 bar differential. An external pilot oil supply and an external pilot oil drain support stable operation, and the pilot section is built in size 6 format. Port T tolerates 250 bar when externally drained, and a ZDR 6 DP0-4X/40YM-W80 pressure reducing valve maintains a constant pilot level. NBR seals provide compatibility with standard hydraulic fluids, and the assembly weight is 13.6 kg including the size 16 subplate.
