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.

Technical data

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.
