Proportional Directional Valve 4WRLE10W8-100LJ-4X/VPT/24F1 - Bosch Rexroth R901476419

Long cable runs between the cabinet and the valve sit badly with a voltage command. The 4WRLE10W8-100LJ-4X/VPT/24F1 therefore takes 4...20 mA and turns that signal into 100 l/min nominal flow at operating pressures up to 350 bar, using its on-board electronics.

Benefits

• 4...20 mA current loop command, powered from 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804.
• 100 l/min nominal flow against a series maximum of 300 l/min, which leaves headroom in the flow map.
• Linear characteristic curve and spool symbol W8 keep signal and flow evenly matched across the full stroke.
• Internal spool position feedback plus internal pilot oil supply and internal return, so no extra piping is needed.
• FKM seals, mounting pattern ISO 4401-05-05-0-05, weight 9.14 kg, CE conformity.

Applications

Typical places are feed and clamping axes on machine tools plus test cylinders where the controller sits far from the valve. At 100 l/min nominal flow the resolution in the part-load range stays fine enough for slow approach movements. FKM seals are made for higher oil temperatures.
