The 4WRZE10E1-85-7X/6EG24N9ETK31/A1D3V valve belongs to the WRZ Proportional Directional Valves series and is produced by Bosch Rexroth. It modulates flow and direction of hydraulic fluid in automated systems. The unit is built for subplate mounting and matches the ISO 4401-05-05-0-94 porting pattern. Size 10 dimensions align with common manifold layouts. The main stage tolerates operating pressures up to 315 bar, while a nominal flow of 85 l/min is achieved when the pressure drop is 10 bar. The valve processes a ±10 V command signal to position the spool proportionally, and the associated electronics are supplied with 24 V DC. Maximum steady current draw is 1.8 A, and the internal circuit can accept power pulse peaks of 3 A during dynamic shifts.
The pilot section is fed and drained internally, and it requires fluid cleanliness of ISO 4406 class 18/16/13 when mineral oil of grades HL or HLP to DIN 51524 is used. An FKM seal set resists the fluid and ambient conditions, and the enclosure meets IP65 for dust-tight and water jet protection. Electrical connection is made through a DIN EN 175201-804 interface, enabling quick plug-in wiring of the coil and electronics. With a mass of 8.0 kg, the valve can be handled by a single technician during installation. These characteristics allow precise directional control in machinery where hydraulic performance and environmental protection must be maintained.
