The 4WRZE10E85-7X/6AG24N9K31/A1D3V proportional directional valve belongs to the WRZ Proportional Directional Valves series produced by Bosch Rexroth for hydraulic motion control. It guides flow in automation loops, and its valve size 10 suits machinery that needs moderate capacity. The mounting interface follows ISO 4401-05-05-0-94, permitting straightforward subplate assembly. A nominal flow of 85 l/min at a 10 bar differential allows efficient throughput, while the main stage endures up to 315 bar to serve high-pressure circuits. Fluid cleanliness must remain within class 20/18/15 under ISO 4406 to protect the precision spool. An IP65 housing shields the electrical section from dust and water jets, and the unit’s weight of 8.0 kg supports stable installation.
Electrical power is supplied at 24 V DC through a DIN EN 175201-804 connector. A ±10 V command signal positions the spool proportionally for accurate flow control, and a 100 percent duty cycle permits continuous energizing. During steady operation the solenoid draws up to 1.8 A, while start-up pulses can reach 3 A to overcome static friction. Coil temperature may rise but must stay below 150 °C to maintain insulation integrity. Internal drainage limits port T pressure to 30 bar and port Y pressure to the same 30 bar, preventing backpressure from affecting spool movement.
