The 4WRZE10E1-85-7X/6EG24N9TK31/A1V valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and provides proportional flow and directional control for hydraulic automation. A nominal size of 10 establishes the port geometry used for installation. The unit passes 85 l/min at a 10 bar differential, matching medium-flow power units. Its hydraulic section withstands operating pressures up to 315 bar, allowing use in high-pressure circuits. Electronic operation requires a 24 V DC supply, and the spool position follows a ±10 V command signal for linear control. Maximum current draw reaches 1.8 A, so the driver electronics must supply this load. Continuous service is supported by a 100 % duty cycle, and the solenoid windings tolerate temperatures up to 150 °C.
Mineral oil of the HL or HLP type is specified as the working fluid, ensuring seal compatibility and lubrication. Pilot oil is fed externally, while an internal T-line drain returns pilot flow to simplify plumbing. The return port handles up to 30 bar back-pressure without damage. Electrical hookup is via a DIN EN 175201-804 connector that provides a quick disconnect option. System cleanliness must be maintained at ISO 4406 class 20/18/15 to protect the metering edges from contamination. A concealed manual override lets maintenance staff shift the spool when power is absent. The assembled subplate version weighs 8.0 kg, a consideration for manifold support and handling.
