The 4WRZE10W6-50-7X/6EG24N9EK31/F1V valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and modulates flow and direction in hydraulic automation circuits. It is built in valve size 10, giving passage areas sized for medium-capacity machines, and it delivers a nominal flow of 50 l/min at a 10 bar pressure drop to move cylinders and motors with predictable speed. A 4–20 mA command input allows proportional spool positioning from standard current controllers, while a 24 V DC supply energizes the solenoid. The coil draws up to 1.8 A, so power supplies must be rated accordingly, and a 100 % duty cycle lets the valve remain continuously actuated without enforced cooldowns. The winding can tolerate coil temperatures up to 150 °C, extending service life under elevated ambient or oil temperatures, and an IP65 housing prevents dust and water jets from affecting operation.
A main-stage pressure limit of 315 bar permits use in high-pressure systems such as presses and mobile machinery. Pilot actuation is handled by a size 6 pilot valve that uses an internal supply with an external drain to keep pilot flow clean and responsive. Hysteresis is kept at or below 6 %, supporting repeatable positioning when the command signal cycles. Wiring is completed through a DIN EN 175201-804 plug, providing a common connector style for industrial harnesses, and a concealed manual override lets maintenance teams shift the spool during power loss without exposing moving parts. FKM seals resist standard hydraulic oils and many synthetic fluids to minimize leakage over long service intervals. The assembled unit weighs 8.0 kg, a factor to consider when mounting on manifolds or subplates.
