The 4WRZE10W6-25-7X/6EG24N9ETK31/F1V valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and regulates hydraulic flow and direction in automated circuits. It is powered by a 24 V DC supply and accepts a 4 to 20 mA command signal so electronic controls can vary spool position proportionally. A coil resistance of 2 Ω at 20 °C supports the current range required for precise metering. Electrical connection is made through the DIN EN 175201-804 interface, allowing quick plug-in wiring. Mounting follows the ISO 4401-05-05-0-94 porting pattern, and the unit is classified as size 10 for manifold compatibility.
Ingress protection is rated at IP65, guarding the enclosure against dust and water jets encountered in machine environments. A 100 % duty cycle permits continuous energization without mandated cool-down periods. The coil can operate up to 150 °C, draws a maximum of 2.5 A, and the on-board electronics consume 1.8 A during normal service. Hydraulic limits include a main pressure of 315 bar and an internal drain return pressure of 30 bar, matched to a nominal flow of 25 l/min when the pressure drop is 10 bar. The valve weighs 8.0 kg and incorporates a concealed manual override (N9) for local movement of the spool when electrical control is unavailable.
