The 4WRZ10E85-7X/6EG24XEJET/D3V proportional directional valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and is engineered to control actuator speed and direction in hydraulic automation loops. Its solenoid operates on a 24 V DC supply, and the coil presents 4.8 Ω at 20 °C, so a driver circuit can predict current draw accurately. Continuous current is limited to 1.5 A, protecting the winding from overload while the insulation can tolerate temperatures up to 150 °C. An IP65 enclosure shields the electrical section from dust and low-pressure water jets, allowing installation in typical plant environments. The unit follows the ISO 4401-05-05-0-94 mounting pattern, which fits common subplates without additional adapters. With a mass of 7.8 kg, routine replacement or service can be performed by a single technician using standard tools.
The hydraulic section passes up to 85 L/min at a 10 bar pressure drop, giving reliable flow capacity for medium-sized cylinders and motors. Main flow paths withstand 315 bar, matching high-pressure power units, and the internal pilot supply is rated to the same 315 bar so no external regulator is needed. Return oil leaves through port T, which must remain below 30 bar, while port Y is also limited to 30 bar to protect the pilot stage. Both pilot supply and drain are taken internally, reducing hose runs on the manifold. A ZDR 6 DP0-4X/40YM-W80 pressure-reducing cartridge is integrated to stabilize pilot pressure for consistent spool positioning. Fluids are sealed with FKM elastomers that resist common hydraulic oils and elevated temperatures.
