The 4WRZE16EA100-7X/6EG24N9ETK31/F1D3V proportional directional valve is manufactured by Bosch Rexroth in the WRZ Proportional Directional Valves series and modulates hydraulic flow to actuators in automated machinery. The valve is built to the NG16 nominal size, providing installation compatibility with mid-frame manifolds. With a nominal flow of 100 l/min at a 10 bar differential, it supplies steady volume for motion tasks. The unit withstands a main pressure of 350 bar so it can operate in high-pressure circuits, while the return port tolerates up to 30 bar to protect tank lines. Internal pilot oil supply and drain eliminate external lines, simplifying manifold layouts. The ISO 4401-07-06-0-94 mounting interface standardizes port geometry for quick block exchange. FKM seals resist common industrial fluids and elevated temperatures, and the hydraulic passages require oil cleanliness at 20/18/15 under ISO 4406 to maintain spool accuracy.
The valve’s solenoid electronics run from a 24 VDC supply, and the metering spool position is commanded with a 4–20 mA signal for integration with typical process controllers. The driver stage limits current to 1.8 A, preventing coil overheating under continuous duty. A DIN EN 175201-804 connector provides the electrical interface so wiring can follow established panel practices. Coil windings are rated for 150 °C, allowing performance in warm hydraulic enclosures. An IP65 housing shields the electronics and coil from dust and water jets encountered on production lines. A concealed manual override lets maintenance staff shift the spool without energizing the coil, aiding troubleshooting. The assembly weighs 13.6 kg, which should be considered when designing manifold supports.
