The 4WRL10E1-80S-3X/G24Z4/M valve belongs to the 4WRL Solenoid Valves series and is produced by Bosch Rexroth for closed-loop hydraulic automation. It fits systems using the ISO 4401-05-05-0-94 mounting pattern and occupies nominal size 10, so it mates with NG10 subplates. The unit is energized by a 24 V DC supply and is wired through a DIN 43560-AM2 plug coded Z4 to simplify field replacement. Passages p, A, and B withstand working pressures up to 350 bar, while ports t, X, and Y are limited to 250 bar, allowing differential routing of return and pilot lines. A minimum pilot pressure of 10 bar keeps the main spool responsive under load, the pilot stage consumes 4 l/min of oil for predictable pump sizing, and full-stroke response is achieved in 25 ms to support fast control loops.
For continuous duty the valve handles process flows up to 170 l/min without exceeding its rated envelope, making it suitable for medium-capacity motion drives. Static accuracy is maintained by a maximum hysteresis of 0.1 percent, so positional drift remains low when the command signal is held. Internal clearances yield a main stage leakage of 400 cm³ per minute at 100 bar, and the pilot stage passes 180 cm³ per minute under the same test conditions; these figures help designers plan reservoir capacity and heat balance. Operation is permitted at ambient temperatures to 50 °C, and the hydraulic fluid may reach 80 °C, extending use in warm machinery bays. Oil cleanliness must meet ISO 4406 class 18/16/13 to protect the precision spool and armature surfaces, and sticking is minimized by the combination of low hysteresis and the specified cleanliness level.
