The 4WRTE10V100L-4X/6EG24EK31/F1M is produced by Bosch Rexroth and belongs to the 4WRTE Directional Control Valves series. Designed to meter flow and direct pressurized oil in automated hydraulic circuits, it uses the NG 10 nominal size to match manifolds and pipework common in medium-capacity systems. With a rated flow of 100 l/min at a 5-bar pressure drop across the control edge, the unit can shift actuators quickly while maintaining low losses. The main stage withstands operating pressures up to 350 bar, while the pilot stage accepts up to 315 bar, so the valve handles high-load cylinders without external pressure reducers. A 24 V DC supply powers the integrated proportional solenoids and electronics, and operation continues down to 18 V DC to accommodate supply dips. To prevent dither from poor power quality, the electronics tolerate a maximum residual ripple of 2.5 Vpp. Electrical demand peaks at 72 VA, which guides fuse and power-supply sizing.
The control electronics draw a continuous current of 1.6 A during normal modulation, and short switching events can reach 2.7 A as impulse current to accelerate the spool. An input resistance of 100 Ω in the command stage matches common controller outputs and limits drive currents. Continuous service is supported by a 100 % duty cycle, so the valve can stay energized indefinitely without forced cooldown. Environmental sealing meets IP65, allowing installation on machinery exposed to dust and water spray. The coil windings are rated for a maximum temperature of 150 °C, and the flow paths accept hydraulic fluid up to 80 °C, giving ample thermal headroom in industrial presses or plastic injection units. Cleanliness requirements correspond to ISO 4406 class 18/16/13, which informs filter selection to protect the precision edges.
