The 4WRAE10E1-60-2X/G24N9K31/A1V valve is manufactured by Bosch Rexroth for the 4WRA Proportional Directional Valves series and regulates hydraulic actuator motion in automated machines. It operates from a 24 VDC supply so that the onboard amplifier can be powered directly from standard control rails. The electronics accept a ±10 V command signal, and the differential input mode reduces common-mode noise when the controller and valve are separated by long cable runs. The amplifier tolerates up to 30 V differential input without damage, while residual ripple on the supply must stay below 2.5 Vpp to keep the spool stable. A peak impulse current of 2.7 A is drawn during rapid shifts, but steady operation is limited to 1.2 A, keeping wiring sizes modest. Overall electrical load does not exceed 24 VA, and the S1 continuous duty rating allows the valve to remain energized without enforced cooling cycles.
The electrical interface is a 6-pole plus protective-earth plug that follows DIN 43563, allowing quick disconnection during maintenance. Upstream power should be guarded by a 4 A time-lag fuse to handle short-duration inrush without nuisance trips. A concealed manual override lets technicians move the spool during commissioning while keeping moving parts shielded in service. The housing carries an IP65 rating, so dust and low-pressure water jets cannot reach internal coils, and FKM seals resist swelling when exposed to common hydraulic oils. Correct fluid filtration is defined by ISO 4406 cleanliness class 20/18/15 to prevent binding of the precision control edges. External surfaces can reach 150 °C under continuous load, so adjacent components must be arranged to respect this thermal envelope.
