The 4WRZE10W50-7X/6EG24N9K31/A1V proportional directional valve is built by Bosch Rexroth within the WRZ Proportional Directional Valves series to regulate flow and direction in hydraulic automation circuits. A nominal size of 10 defines the port geometry, and the ISO 4401-05-05-0-94 mounting pattern lets the unit bolt to standard subplates without adapters. A nominal flow capacity of 50 l/min at a 10 bar differential supports medium-duty actuator motion, while a main pressure rating of 315 bar allows use on high-pressure supply lines; the Port T external drain is rated for the same 315 bar to handle back-pressure reliably. The pilot stage is size 6 and uses an external pilot oil supply, so a separate piloting line is required for operation. An overall weight of 8.0 kg must be considered when selecting manifold brackets and service tools.
The internal electronics run on a 24 V DC supply voltage, and a ±10 V command signal provides proportional spool control for closed-loop systems. Maximum OBE current consumption of 1.8 A specifies the load on the machine’s power rail. A DIN EN 175201-804 electrical connector gives a keyed interface for wiring. Valve hysteresis is held to ≤ 6 percent, limiting deviation between the commanded and actual flow. A concealed manual override labeled N9 enables emergency actuation without altering the valve’s external profile. The enclosure carries an IP65 protection class so it can operate in dusty or wet plant areas. FKM seal material resists common hydraulic fluids and elevated temperatures, ensuring long service life at the rated pressures.
