The 4WRZ10W8-50-7X/6EG24N9ETK4/M proportional directional valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and modulates flow direction and volume in hydraulic automation loops. Its nominal size 10 defines passage dimensions that suit medium-capacity circuits, while the ISO 4401-05-05-0-94 mounting interface allows direct fitting to standard subplates. A nominal flow of 50 l/min at a 10 bar differential gives predictable actuator speed, and a maximum operating pressure of 315 bar sets the inlet pressure ceiling. Internal supply and drain for pilot oil eliminate external pilot lines, reducing installation time. The 24 V DC supply voltage matches common control cabinets; with a coil resistance of 4.8 Ω at 20 °C and a maximum current of 1.5 A, the electromagnet stays within typical driver capabilities.
A 100 % duty cycle lets the coil remain energized continuously, and a maximum coil temperature of 150 °C limits thermal stress on the winding insulation. The DIN EN 175301-803 (K4) electrical connector provides a plug-in interface for quick wiring. An IP65 ingress protection rating shields the enclosure from dust and water jets encountered on machinery. A concealed manual override identified as N9 allows spool actuation during setup without increasing external dimensions. The internal drain line tolerates up to 30 bar return pressure, protecting the housing seals. NBR sealing material marked as M supports standard mineral oil fluids, and a subplate weight of 7.8 kg for size 10 factors into mounting bracket design.
