The 4WRZE10W6-50-7X/6EG24N9K31/F1D3V valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and is used to meter flow and set direction in automated hydraulic circuits. Its size 10 format defines the port spacing and envelope needed for mid-range actuator groups, while the ISO 4401-05-05-0-94 mounting interface lets the body bolt directly to standard sub-plates without adapters. A nominal flow of 50 l/min at a 10 bar pressure drop supports moderate throughput in machine tools or presses, and the main stage tolerates operating pressures up to 315 bar so high-pressure pumps can be used without derating. The external pilot stage is limited to 100 bar to protect the control orifice from overload. Electrically, a 24 V DC supply energizes the solenoid, and current draw is capped at 1.8 A to match common power supplies on mobile equipment. The coil shows 2 Ω resistance when cold, giving predictable inrush characteristics. Wiring is completed through a DIN EN 175201-804 connector that provides a secure, keyed interface for field cabling.
The valve carries an IP65 protection rating, keeping dust and low-pressure water jets from reaching internal coils during wash-down or outdoor service. Continuous operation is allowed until the coil reaches 150 °C, giving thermal headroom for hot oil environments. Flow accuracy is supported by a hysteresis value not exceeding 6 percent, so commanded spool positions repeat within tight limits. Port T can handle 315 bar when an external drain is used, allowing return flow to share the main system pressure, whereas port Y is restricted to 30 bar to safeguard the internal pilot drain path. FKM seal material resists synthetic and mineral hydraulic fluids, maintaining elasticity over wide temperature ranges. The assembled unit weighs 8.0 kg, a mass that one technician can manage during installation without lifting aids.
