The 4WRLE10V85M-3X/G24K0/A1M valve is part of the 4WRL Solenoid Valves series produced by Bosch Rexroth for electro-hydraulic automation where proportional flow control is required. It is built in nominal size 10 so it matches medium frame subplates and circuits with moderate port dimensions. The spool carries symbol V, and, combined with the M progressive flow characteristic, it provides a gradual increase in flow as the command signal rises. With a rated flow of 85 l/min at a 10 bar differential, the valve supports high actuator speeds, yet its zero-lap design limits leakage to 1.7 l/min when centered. The main ports withstand operating pressures up to 350 bar, while return ports T and Y are limited to 250 bar to protect tank lines. All dynamic seals are formed from NBR, ensuring compatibility with standard mineral hydraulic oils.
Electrical actuation accepts a ±10 V command input so that external controllers can position the spool proportionally, and the electronics operate from a 24 VDC supply that is common in industrial cabinets. The amplifier presents an input impedance of 100 kΩ to minimize loading on signal sources. Static hysteresis does not exceed 0.1 %, allowing repeatable metering after direction reversals, and response sensitivity of 0.05 % enables fine resolution of small set-point changes. Continuous service is possible because the solenoid system is rated for a 100 % duty cycle, and maximum power consumption stays within 40 VA, which simplifies power budgeting in multi-axis machines. A molded connector and sealed housing give the assembly an IP65 protection class, preventing dust ingress and low-pressure water jets so the valve can be mounted directly on machinery without additional enclosures.
