The 4WRTE10E1-100L-4X/6EG24ETK31/A1M valve belongs to the 4WRTE Directional Control Valves series from Bosch Rexroth and directs hydraulic flow in automated machinery. The NG10 size offers standardized port spacing for mid-range manifolds, while a rated flow of 100 l/min at a 5-bar control edge supports cylinders that demand moderate speed. A linear flow characteristic converts spool stroke into predictable volume change and simplifies loop tuning. Operating pressure reaches 350 bar on ports P, A, and B, enabling use in high-pressure presses. Both pilot oil supply and pilot oil return are internal to reduce external plumbing, and the pilot stage accepts pressures up to 315 bar. NBR seals confine mineral oil and withstand common hydraulic additives.
Embedded electronics accept a 24 VDC supply, and a ±10 V command signal positions the spool for proportional control. The input circuit shows 100 kΩ resistance, keeping load on the control card low, and the board tolerates up to 35 VDC with a maximum draw of 1.6 A. Wiring is completed through a DIN EN 175201-804 K31 connector that fits standard harnesses. The enclosure carries an IP65 rating to block dust and low-pressure water jets, allowing installation close to process areas. Overall weight is 8.7 kg, so a single technician can fit the valve during routine maintenance.
