The 4WRTE10V100L-4X/6EG24TK31/A1M valve belongs to the 4WRTE Directional Control Valves series from Bosch Rexroth and is intended to modulate flow and pressure in hydraulic automation loops. It operates on a 24 V DC supply so it can tie directly into common machine control buses, while a maximum power draw of 72 VA keeps electrical loading predictable. During continuous duty the electronics limit consumption to 1.6 A, yet a time-lag fuse rated at 4 A safeguards the circuit against inrush or fault conditions. The built-in amplifier presents an input resistance of 100 kΩ so standard command cards can drive the spool without excessive load, and the permissible residual ripple of 2.5 Vpp ensures stable positioning even with mildly noisy supplies. A short 2.7 A impulse current accommodates rapid spool shifts before settling to steady-state, and an IP65 housing blocks dust and water jets, allowing installation on exposed manifolds.
The metering section delivers a rated flow of 100 l/min for normal duty cycles, while applications demanding brief higher throughput can utilize the recommended maximum of 170 l/min without exceeding accuracy limits. A pilot oil demand of 7 l/min across the 0–100 % control range minimizes auxiliary pump sizing, and the assembly withstands operating pressures up to 350 bar so it can serve high-pressure circuits. Coil insulation tolerates temperatures to 150 °C, preventing thermal drift during prolonged energization. The valve mounts on subplates following the ISO 4401-05-05-0-05 pattern, simplifying interchange with other modular components. Hydraulic cleanliness must reach ISO 4406 18/16/13 to avoid spool sticking or accelerated wear, and the overall weight of 8.7 kg provides sufficient mass to damp vibration while remaining manageable for single-person servicing.
