The 4WRZE10E50-7X/6EG24N9K31/F1V is a proportional directional valve in the WRZ Proportional Directional Valves series from Bosch Rexroth, intended to meter and switch hydraulic flow in automated machinery. Its nominal size is 10, which sets the mounting and passage dimensions for medium-capacity circuits. A nominal flow of 50 l/min at a 10 bar pressure drop defines standard throughput, while the main stage can pass up to 170 l/min to cover momentary demand spikes. The main ports withstand operating pressures as high as 315 bar so the unit can serve high-pressure actuators. Electrical control is supplied by 24 VDC; a coil resistance of 2 Ω at 20 °C and a maximum current draw of 1.8 A guide driver selection. Continuous service is supported by a 100 % duty cycle, and wiring is made through a DIN EN 175201-804 connector for compatibility with common harnesses.
A command value overlap of 15 % sets the dead-band around the neutral point, allowing predictable null behavior, while maximum hysteresis is limited to 6 % to keep flow repeatability within tight bounds. The coil can tolerate temperatures up to 150 °C, so thermal excursions during continuous energization do not compromise insulation life. An IP65 protection class blocks dust ingress and low-pressure water jets, permitting installation on open machine frames. Port Y is rated for 30 bar to ensure reliable pilot drainage, and return flow to port T can reach 315 bar without risking case leakage. The supplied subplate weighs 8.0 kg, adding rigidity for stable mounting beneath the valve body.
