The 4WRZE10E50-7X/6EG24N9EK31/F1V valve belongs to the WRZ Proportional Directional Valves series manufactured by Bosch Rexroth for hydraulic automation that needs precise spool positioning. It accepts a 4 to 20 mA command signal so a controller can vary flow proportionally, and it runs from a 24 V DC supply that matches common mobile and industrial power systems. The maximum solenoid current is limited to 2.5 A, while a coil resistance of 2 Ω at 20 °C establishes predictable current draw. Continuous service is possible because the duty cycle is rated at 100 percent, and the coil can endure temperatures up to 150 °C without degradation. Wiring uses a DIN EN 175201-804 connector that speeds installation, and an IP65 housing blocks dust ingress and low-pressure water jets for reliable field use.
The valve attaches to manifolds through an ISO 4401-05-05-0-94 interface, and its nominal flow reaches 50 l/min at a 10 bar pressure drop to serve medium-capacity actuators. Operating pressure can rise to 315 bar, allowing deployment in high-pressure circuits. Pilot oil is supplied internally to simplify plumbing, while an external pilot oil drain routes leakage directly to tank to avoid back-pressure on the pilot stage. A concealed manual override lets maintenance personnel shift the spool during commissioning or power loss, and FKM seals withstand standard hydraulic fluids and elevated temperatures. The total valve weight is 8.0 kg, a factor to consider when calculating manifold load capacity.
